The UTfit Collaboration has produced several analyses in the context of flavour physics both within and beyond the Standard Model. In this paper we present updated results for the Standard Model analysis of the Unitarity Triangle using the latest experimental and lattice QCD inputs, as well as an update of the Unitarity Triangle analysis in a scenario beyond the Standard Model. Combining all available experimental and theoretical information on ΔF=2 processes and using a model-independent parameterization, we extract the allowed New Physics contributions in the K0, D0, Bd, and Bs sectors. We observe a departure of the Bs mixing phase from the Standard Model expectation with a significance of about 3σ.

Abstract

The UTfit Collaboration has produced several analyses in the context of flavour physics both within and beyond the Standard Model. In this paper we present updated results for the Standard Model analysis of the Unitarity Triangle using the latest experimental and lattice QCD inputs, as well as an update of the Unitarity Triangle analysis in a scenario beyond the Standard Model. Combining all available experimental and theoretical information on ΔF=2 processes and using a model-independent parameterization, we extract the allowed New Physics contributions in the K0, D0, Bd, and Bs sectors. We observe a departure of the Bs mixing phase from the Standard Model expectation with a significance of about 3σ.
