eyond the Standard Model at the Intensity Frontier (working title)

Department Name: Sch of Mathematical & Physical Sciences
Abstract
Naturalness and other considerations suggest new degrees of freedom at or near the TeV energy scale. Such degrees of freedom can be probed through precision indirect observables, such as rare flavour-changing and CP-violating processes.
We will follow a two-pronged approach. We will develop bottom-up, model-independent analyses based on current and future experiments, inspired in part by anomalies in the LHCb data set and comprising technical and phenomenological work. This will be complemented by and connected to model-dependent studies, of supersymmetric and/or partial-composite extensions of the Standard Model.
This project is part of a programme that ultimately aims to identify the successor of the Standard Model.

PI Contribution | I have worked collaboratively on a project which studies the connection between rare B meson decays and B mixing and lifetime observables which receive contributions from charmed couplings. I have performed various perturbative calculations for observables such as the B_s meson lifetime, the decay rate difference and effective Wilson coefficients arising from b->sll and b->s gamma transition. I have cross checked others work independently and performed my own calculations which have been cross checked by others. I have played a role in discussion of the direction of the project, the writing/ editing of our first publication. |
Collaborator Contribution | Collaborators have contributed by providing NLO values for mixing and lifetime observables, by calculating two loop contributions and the writing and submission of our publication. |
