Flavourful SMEFT likelihood for Higgs and electroweak data
Adam Falkowski, David Straub
We perform an updated fit to LHC Higgs data and LEP electroweak precision tests in the framework of the Standard Model Effective Field Theory (SMEFT). We assume a generic structure…

Flavor Physics and Flavor Anomalies in Minimal Fundamental Partial Compositeness
Francesco Sannino, Peter Stangl, David M. Straub +1
Partial compositeness is a key ingredient of models where the electroweak symmetry is broken by a composite Higgs state. Recently, a UV completion of partial compositeness was prop…
WCxf: an exchange format for Wilson coefficients beyond the Standard Model
Jason Aebischer, Ilaria Brivio, Alejandro Celis +11
We define a data exchange format for numerical values of Wilson coefficients of local operators parameterising low-energy effects of physics beyond the Standard Model. The format f…
Future prospects for exploring present day anomalies in flavour physics measurements with Belle II and LHCb
