Abstract

We present a likelihood analysis of the general two Higgs doublet model, using the most important currently measured flavour observables, in view of the anomalies in charged current tree-level and neutral current one-loop rare decays of B mesons in b → clv and b → sμ+μ transitions, respectively. Our analysis predicts values for BR(ℎ → τμ) between 10−2 and 10−6 which are within the future sensitivity at the High Luminosity LHC. We also find that the predictions for the τ → 3μ and τ → μγ decays are well within the projected limits of the Belle II experiment with a discovery potential for BR(τ→ 3μ) ∼ 10−9 and BR(τ → μγ) ∼ 10−9 − 10−8. Using the latest measurement of the Fermilab Muon g − 2 Collaboration, we also perform a simultaneous fit to the muon anomalous magnetic moment and both observables related to flavour changing currents and leptonic decays of mesons, finding solutions at the 1σ level.

OtherThis workshop aims to review the state-of-the-art tools for high energy physics and cosmology.
The workshop consists of short sessions over 5 days together with software demo and several discussion sessions.

The following themes will be covered at the workshop:

Higgs and Collider physics
Dark matter
Cosmology
Flavour physics and precision tests
General tools (Fitting tools, recast tools, spectrum generators, etc...)

The program will consist of both invited talks and contributed talks and tutorials.
