Higher order corrections for low energy hadronic cross sections and electron-muon scattering
- Supervisors: Prof Graziano Venanzoni Prof Thomas Teubner
The muon anomalous magnetic moment g-2, where g is the gyromagnetic ratio of the muon, is one of the exceptional cases in particle physics at low energy where a significant discrepancy between measurement and Standard Model (SM) prediction has persisted for more than 20 years. This discrepancy, now reaching 4.2 sigma, could be a compelling evidence of physics beyond the SM. In view of the new experimental efforts under way at Fermilab (USA) and J-PARC (Japan) to improve the g-2 accuracy, a confirmation of its SM prediction is now mandatory. Its hadronic contributions are under particular scrutiny, as they induce the main uncertainty of the SM prediction.
For this it is crucial to better determine the radiative corrections which are needed to describe processes like e+e- -> hadrons+gamma and electron-muon scattering. This PhD project is therefore focused on perturbative higher order calculations and their phenomenological application to these processes. It may also include work on the development of Monte Carlo generators for these processes.
The successful candidate will work in the Theoretical Physics group and work with experienced researchers and senior academics. They will become part of the fast-growing research group on muon precision physics in Liverpool, with several related projects across theoretical and experimental particle physics.
