First implications of LHCb data on models beyond the Standard Model

TL;DR

This paper analyzes LHCb's 2011 data results on CP-violation and rare decays to explore implications for models beyond the Standard Model, proposing strategies for future constraints.

Contribution

It provides a detailed discussion of experimental results and introduces new methods to constrain beyond Standard Model theories using these findings.

Findings

Measurement of CP-violation in B_s -> J/psi phi

Upper limits on B_(s) -> mu+ mu- decays

Strategies for constraining New Physics models

Abstract

We discuss the theoretical and experimental details of two of the main results obtained by LHCb with the 2011 data, namely the measurement of the mixing-induced CP-violation in the decay B_s -> J/psi phi and the upper limits on the decays B_(s) -> mu+ mu-. Then we describe the possible strategies to obtain new constraints on two different New Physics models in the light of these results.
