Biography

Themis Bowcock currently leads the Particle Physics Group.

He received his PhD from Queen Mary College, London in 1984 on the UA1 experiment at CERN, (which found the W/Z particles); his research was on hadronic jets and the gluon structure function.  He became a Research Associate at Harvard on the CLEO experiment from 1984-1989 where he studied the production charm, B-mesons and searched for exotic particles including axions and monopoles. From 1989-1991 he was an Assistant Professor at Texas A&M University where he worked on the CDF experiment and received an SSC fellowship. During this period he worked on knife edge chambers - an early precursor MSGCs.

Moving to a Lectureship at Liverpool in 1991 he worked on DELPHI at LEP, first measuring B-lifetimes using the micron-vertex detector and then studying Trilinear Gauge Couplings. In the mi-1990's he co-proposed the use of silicon for the end-cap on ATLAS.

In 1997 he started the LHCb group on LHCb and was responsible for the design and construction of the LHCb VELO which was completed in 2007.

From 2001-2003 he conceived of and led the Liverpool Monte Carlo Array Processor project which was the first large scale use of commodity computing in HEP; MAP2 briefly reached to top 50.  In 2004 He co-founded the AiMeS Institute at Liverpool for the commercial application of Grid Technologies.

Having led and helped commission the  VELO  at CERN from 2009-2011 his main physics interests lie with LHCb where he is studying top production. His future plans include the LHCb Upgrade at CERN, the g-2 experiment at Fermilab and a terrestrial search for Dark Energy in Liverpool

Biography

 John is an Experimental Particle Physicist whose work focuses on the structure and dynamics of sub-nuclear matter. For more than three decades he has been intrigued by the way in which matter as we know it is constituted, namely how Dirac fermions – quarks - make up the hadrons of which we and the Universe is made.

His first experiment aimed at untangling the spectroscopy of the then heaviest of three known quarks, the “strange” quark. Since then he has been concerned with measurements of the interactions of photons and electrons with matter and how the Standard Model understand and explains such interactions in terms of the fundamental gauge theories, chromodynamics and electroweak dynamics, in terms of the interactions of three generations of leptons and quarks and the field quanta, gluons, massive vector bosons and photons. His experiments have been at remote laboratories, Daresbury Lab in the UK, CERN in Geneva, and DESY in Hamburg Germany as well as his home base in Oxford, Glasgow and Liverpool Universities.

He was spokesperson of the H1 experiment (1997) at the HERA ep collider, awarded of the Max Born Medal of the Institute of Physics (1999), and electioned to the Fellowship of the Royal Society (2002).

He has contributed to the resurgence of R&D in sub-nuclear and nuclear particle acceleration and beam delivery by leading the Foundation of the Cockcroft Institute, an innovative research centre funded jointly by the Universities of Lancaster, Manchester and Liverpool with the UK Science and Technology Facilties Council, and with regional and European support.  He is now engaged in measurements of extremely rare kaon-decays, branching ratio of order 10-11 or less, as a means of discovering a breakdown of the Standard Model with an indication of the energy scale of new physics responsible for it.

Biography

Tim Greenshaw started his research career at Manchester University, working with the JADE collaboration, where he studied e+e- collisions at the PETRA collider in Hamburg. He had a particular interest in measuring the forward-backward asymmetry in the production of both heavy and light quarks and using these measurements to extract the weak coupling constants of the quarks.

He then took up a position with  Hamburg University and started work with the H1 collaboration, studying ep collisions at HERA. Here, he investigated aspects of QCD, for example studying “rapidity gaps” in the hadronic final state. He then moved to Liverpool University, but continued working with H1, where he was responsible for the upgrade of the H1 Forward Track Detector. This ensured the FTD was able to cope with the increased luminosity HERA delivered in its second phase of running.  

Tim was Deputy Spokesperson of H1 from 2003 until 2005. He returned to the study of e=e- collisions, leading the Linear Collider Flavour Identification collaboration from 2006 until 2009. LCFI developed sensors, readout and mechanical support structures for the Vertex Detector of the International Linear Collider, and investigated the physics that this detector could be used to study.

After the termination of this project (the UK pulled out of the ILC because of funding difficulties), he joined the ATLAS collaboration. Here, he carried out investigations for the silicon tracker upgrade, for example simulating the effects of radiation damage on the sensors used in this detector.

Since 2010, his primary research interests have been with the Cherenkov Telescope Array, which is an international consortium designing apparatus to study photons from cosmic sources that have energies in the range from a few tens of GeV to several hundred TeV. He currently leads the design and prototyping phase of the Small Sized Telescope section of the array, which will detect the highest energy photons CTA observes. His physics interests here include searches for axions and the using CTA measurements to study the Extragalactic Background Light.

 Max.Klein@liverpool.ac.uk

Biography

In the past 40 years, Max Klein particularly concentrated on the investigation of the inner structure of the proton. In the 1990s, he played a decisive role in the discovery of a surprisingly large gluon component, an element of the proton.  The gluons are important in the generation of Higgs bosons; a promising candidate of these particles was recently detected at CERN.

After first experiments in Dubna, already in the 1980s Klein joined experiments at DESY in Hamburg and CERN. Since 1985, he is a member of the H1 collaboration at DESY’s storage ring HERA. From 2002 to 2006, Klein was head of the H1 collaboration and he guided the project into a new era of precision measurements of the proton structure and tests of the elementary particle physics standard model. Since 2006, Klein works in England and is Chair for Particle Physics of the University of Liverpool. During his whole career, Klein was a tireless forerunner in the field of lepton-nucleon scattering. Still today, he plays a leading international role in the planning of a next generation scattering experiment.

In 2012 the German Physical Society (DPG) awarded the Max Born Prize to Professor Max Klein for his fundamental experimental contributions to reveal the structure of the proton through deep inelastic scattering.

Biography

Jan Kretzschmar started his research in experimental particle physics in 2003 at DESY Zeuthen, Germany. He joined the H1 experiment at the HERA collider in Hamburg, Germany. He contributed to the construction and commissioning of the forward and backward silicon trackers. His analyses were aimed at precision understanding of the structure of the proton and the theory of strong interactions, Quantum Chromodynamics (QCD).

After completion of his PhD in 2008, he was awarded a PPRAC Fellowship and moved to Liverpool to join the ATLAS experiment at the LHC. In 2011 he was given a lectureship at Liverpool University.

His current main area of research within the ATLAS collaboration are precision measurements of W and Z production as a tool to test QCD and the proton structure in a new energy regime. He is co-convening the efforts to understand the electron performance at the best possible level to enable these precision measurements. Furthermore he is involved in searches for new heavy di-lepton resonances at the energy frontier. He is also actively contributing to the testing and improving of Monte Carlo generators as indispensable tools for both precision measurements and searches.

Biography

Neil McCauley is a reader in the physics department and is a member of the neutrino group conducting research into these most elusive of fundamental particles. Neil began his career as a member of the Sudbury Neutrino Observatory (SNO) collaboration and was a member of the team that solved the 30 year old solar neutrino problem.

Data from SNO demonstrated that neutrinos change flavour as they travel from the centre of the Sun to the Earth and this discovery is one of the central planks of experimental evidence for neutrino oscillations. Upon joining Liverpool in 2006 Neil joined the T2K experiment which measures neutrino oscillations in a neutrino beam sent 295 km across Japan from JPARC to Kamiokande. Data from T2K has demonstrated full three generational mixing via the appearance of electron neutrinos in the muon beam and continues to collect data to greatly improve the precision of our knowledge of neutrino oscillations.

Neil plays a leading role in this effort as the convener of the near detector electron neutrino group measuring the most important background in the experiment. Looking to the future for the next generation of experiments Neil is a member of the LAGUNA-LBNO group working on the design of the next generation long baseline experiment which will further illuminate the neutrino sector with the search for CP violation in neutrinos. Finally to further understand neutrino physics Neil is a member of the SNO+ experiment, building on his expertise with the SNO detector. SNO+ searches for a new type of radioactive decay, neutrinoless double beta decay, which can tell us about the absolute neutrino mass scale and will answer a specific question on the properties of neutrinos: are neutrinos their own anti-particle.

Biography

Andrew is a reader in experimental particle physics. His current interest lies in Higgs searchs using the ATLAS experiment at CERN. He showed that the Higgs decay to bottom quarks could be observed if produced with and associated W or Z boson. He has subsequently made several searches in this channel. His work together with colleagues from Liverpool greatly improved the  number of  Higgs that decay to Zs that could be observed if the Higgs mass was large. All this work contributed to to the observation of a Higgs-like particle in 2012.

He previously worked on the  H1 experiment in Hamburg, where he made numerous measurements that have helped us understand the structure of the proton. For his thesis he made the first measurement of diffractive deep inelastic scattering, which helped us understand the class of events where the proton remains intact.  His subsequent  measurements showed that this type of interaction was dominated by an exchange object composed predominately of gluons. He made measurements of the proton structure function that were used to set limits on the quark size. He made the first measurement of the bottom quark structure function and  devised a new experimental technique to produce a more precise charm structure function.  
He is also a member of the CDF experiment in Fermilab, Chicago. His measurements of the bottom quark in association with a Z boson, helped our understanding of heavy flavour production in hadronic collisions.

Biography

Christos Touramanis is the Head of Department of Physics, deputy Head of the Particle Physics Group, Chair of the CERN LHC Resources Scrutiny Group and member of the Governing Board of the University of the Aegean (Greece).

He received his PhD from the Aristotle University of Thessaloniki  in 1992 on the CPLEAR experiment at CERN; his research was on Fundamental Symmetries (CP, CPT) using tagged neutral Kaons and their antiparticles. He was awarded a CERN Fellowship in 1993.

In 1997 he moved to Liverpool with a PPARC Advanced Research Fellowship and joined the BABAR experiment at SLAC. He contributed directly to the discovery of CP Violation in the B meson system in 2001 which led to the 2008 Nobel Prize to Kobayashi and Maskawa. He pioneered the measurement of the "Unitarity Triangle" angle alpha using the decays of B mesons to a pair of rho mesons. In 2001 he became Head of the Liverpool Quark Flavour group which made key contributions to the first observations of rare B decays, the first observation of Direct CP Violation in the B meson system and the mixing of D mesons.

In 2004 he initiated the Liverpool neutrino group and joined the KM3NeT consortium and the T2K long baseline experiment in Japan. He is responsible for the T2K Near Detector Electromagnetic Calorimeter, the biggest particle detector ever constructed in Europe for an experiment in the Far East. The detector was designed and constructed in the UK and is operating at J-PARC since 2010. He was Project Manager for the UK participation in T2K construction (£15M) and then Analysis co-Coordinator for the Near Detector and member of the Analysis Steering Group of T2K.

His activities include the development of security applications for the detection of special nuclear materials (MODES-SNM), R&D in Liquid Argon detectors and design studies for future long-baseline experiments to search for CP Violation in neutrinos (LAGUNA-LBNO).
