I am a Professor in Experimental Particle Physics at the School of
Physics and Astronomy . These are the courses I am currently teaching:
My main research activity is on the LHCb experiment that has been data taking since 2009 at the Large Hadron Collider (LHC) at CERN in Geneva, Switzerland. The aim of the experiment is to measure differences in the decay of B-mesons (quark-antiquark states containing the beauty quark) with respect to their antiparticle partners. The mechanism that governs the difference between B and anti-B decays is called CP violation and is thought to be the mechanism that allowed matter to dominate over antimatter at an early stage in the formation of the universe. It is thought that there might be some new physics effect that might solve this puzzle. In the LHCb experiment we will test the internal consistency of the Standard Model theory of CP violation and, hopefully, discover new physics phenomena. Furthermore, LHCb has made a large number of measurements on rare hadron decays and has made discoveries of new particles and states at the LHC.
I also work in neutrino physics and the search for CP violation in the neutrino sector. There are three types of neutrinos that are known (electron-, muon- and tau- neutrinos). Neutrinos oscillate from one type to another, due to mixing between the types of neutrinos. CP violation may also be measured for neutrinos by comparing the rate of oscillations of neutrinos and antineutrinos. To achieve this, one needs accelerators that can produce huge numbers of neutrinos. I participate in a programme of R&D to develop a neutrino factory some time in the future that would deliver beams of neutrinos of sufficient intensity to measure all the mixing parameters of neutrinos and, ultimately, discover CP violation in the neutrino sector. My activities in neutrino physics include:
