PhD project: Electromagnetic corrections to hadronic amplitudes
The strong interactions being $\sim 100$ times stronger than the electromagnetic interaction, the isospin symmetry where the up and down quark are considered as neutral and identical particles is generally a good approximation for hadronic processes. However, lattice simulations are now reaching a level of precision close to the percent and isospin breaking effects, generally not implemented in simulations, are becoming the dominant source of uncertainty. Moreover, after the spectacular success from the LHC to check the Standard Model of particle physics to a very high degree of accuracy, it is clear that new physics needs to be found though precision measurements. It is therefore crucial to be able to produce very high accuracy Standard Model predictions, especially for hadronic processes. This project focus on setting up a theoretical and technical framework to allow simulations of various hadronic leptonic and semi-leptonic decays to allow for constraints on the CKM matrix coefficients beyond the percent level. A first step would be to study kaon decays and on a longer term perspectives $D$ and $B$ decays.
This project is supported by the European Research Council (ERC) under the European Union's Horizon 2020 research and innovation programme under grant agreement No 757646 "Search for new physics through lattice simulations". Through this funding there is limited support for a non-EU scholarship specifically for this project.
The project supervisors welcome informal enquiries about this project.
