Search for Pure Leptonic B Decays at ATLAS and CMS

TL;DR

This paper reports on the search for rare leptonic B meson decays at the LHC, providing upper limits on their branching fractions based on 2011 ATLAS and CMS data, which are crucial for testing new physics models.

Contribution

It presents the first combined analysis of ATLAS and CMS data on $B_{s,d}^0 o \mu^+\mu^-$ decays, setting upper limits on their branching fractions.

Findings

Established upper limits on $B_{s}^0 o \mu^+\mu^-$ and $B_{d}^0 o \\mu^+\\mu^-$ decay branching fractions.

Provided constraints on new physics models beyond the Standard Model.

Analyzed 7 TeV proton-proton collision data from 2011.

Abstract

The rare decays $B_{s,d}^0 \to \mu^+\mu^-$ are important probes for new physics beyond the Standard Model. These decays are subjects of studies at the LHC. The ATLAS and CMS collaborations have analyzed the proton-proton collisions data at 7 TeV centre-of-mass energy collected in the year 2011. They have established upper limits on the branching fractions of the two decays. This paper presents a report.
