Exploring B-physics anomalies at colliders

Abstract

Several experimental measurements of $B$ meson decays, in tension with Standard Model predictions, exhibit large sources of Lepton Flavour Universality violation. We perform an analysis of the effects of the global fits to the Wilson coefficients assuming a model independent effective Hamiltonian approach, by including a proposal of different scenarios to include the New Physics contributions. Both the current fits at the LHC and the ILC projections are considered. We found that for a simultaneous analysis of predictions for the $R_{D^{(\ast )}}$ and $R_{K^{(\ast )}}$ observables, the scenarios with three non-universal Wilson coefficients are favoured.
