Description

The study of high-$p_T$ tails at the LHC can be a complementary probe to low-energy observables when investigating the flavour structure of the Standard Model and its extensions.
Motivated by the $B$ anomalies, we study the interplay between low-energy observables and both charged and neutral current Drell-Yan measurements, and their implications for semileptonic interactions.
The Mathematica package "HighPT" allows to do so within a unified and consistent framework, yielding a likelihood function that includes not only high-$p_T$ and flavour observables, but the EW pole and Higgs observables as well, thus allowing to perform combined fits easily.
We discuss such combined analyses in the Effective Field Theory approach.
