Particle Physics Experiment

Our strategy is to search for evidence for new physics through the production of new particles at the energy frontier, and through precision studies of flavour physics. We are very active participants in the ATLAS and LHCb experiments at the Large Hadron Collider (LHC) at CERN. In LHCb we led the construction and commissioning of the Ring Imaging Cherenkov (RICH) detectors, and in ATLAS we contributed to the monitoring of the tracking and trigger systems. In both experiments we have leading roles in management, core computing and data analysis.

In 2011/12 ATLAS recorded 27/fb of proton-proton collisions at 7-8TeV, from which 248 papers have been produced. We were directly involved in the discovery of the Higgs boson, analysing the ZZ* to 4 lepton channel, and gave one of the first conference talks (QCD12, Montpellier). We are searching for H to bb decays using boosted WH and ZH production, and for H to WW to confirm the nature of the Higgs. In 2011/12 LHCb recorded 3/fb of data from which 113 papers have been produced. The LHCb highlight is the first accurate measurement of matter-antimatter asymmetries (CP violation) in Bs meson decays, an analysis we led and gave the first conference talk (Moriond EW 2012). We are extending our work on CP violation to rare B decays that are expected to be more sensitive to new physics contributions, and have produced some first results.
