Particle Physics Theory

Our strategy is centred on phenomenological studies that are of direct relevance to the physics being investigated in high-energy experiments, and in particular at the LHC. These include theories both within and beyond the Standard Model. We have expanded our work on lattice field theory in several directions with finer lattices and dynamical fermions at the physical light quark masses.

We have collaborated with IBM on the development of a new generation of BlueGene supercomputers and have used these to compute non-perturbative Quantum Chromodynamics (QCD) parameters that are important in flavour physics. We have developed lattice theories that are candidates for strong electroweak symmetry breaking. We have used perturbative QCD to deliver robust parton distribution functions with LHC data. These are key inputs used by all the LHC experiments for determining production rates for new particles, including the Higgs boson. We have provided Monte Carlo tools for the improved description of multijet events. We study theories beyond the Standard Model and their implications for anomalous results from the LHC experiments. Other activities include algebraic properties of gauge amplitudes, aspects of fundamental field theories, baryogenesis and inflationary cosmology.
