Description
Precision measurements in particle physics provide an alternative insight into physics beyond the Standard Model, complementary to the push to higher energies at the LHC. Large increases in precision are enabled by the availability of intense muon beams, utilised in many experiments including searches for charged lepton flavour violation in a variety of different channels in MEGII, Mu3e, Mu2e and COMET aiming for improvements in the current world’s best limits of up to 10^4. The muon g-2 experiment, also making use of these muon beams has now published its final result, reaching unprecedented precision of 127ppb, exceeding the goal of the experiment. There is a lot of work currently ongoing to understand discrepancies in the theoretical prediction both in the experimental and theory community, this talk will touch on some of the efforts such as MUonE, analysis of the KLOE data and the JPARC g-2 experiment.
The muon g-2 experiment is also expected to publish a new world leading limit on the muon EDM. In the Standard Model particles are predicted to have zero EDM, but many new physics models result in slightly non-zero values and precision measurements of these quantities can give insight into potential new particles which could resolve some of the outstanding questions, such as the matter-antimatter asymmetry in the universe. This talk will discuss some of these efforts to measure the EDMs of the electron, muon, neutron and proton.
The world of precision particle physics is vast, with large increases in precision achieved and expected in the near future. This talk will attempt to discuss some of these results with a focus on the work that is being done in the UK to uncover the new physics we are searching for.
