Measurements of Rare B Decays at Tevatron

TL;DR

This paper reports on searches for rare B meson decays at the Tevatron collider, aiming to find evidence of physics beyond the Standard Model through flavor-changing neutral current processes.

Contribution

It presents recent experimental results on rare B decay modes, focusing on FCNC processes, from the CDF and DØ collaborations at Fermilab.

Findings

No evidence of FCNC B decays observed.

Limits set on branching ratios of rare B decays.

Constraints on new physics models derived from measurements.

Abstract

Both CDF and D{\O}experiments have been searching for evidence of physics beyond the standard model (SM) using the Tevatron $p\bar{p}$ collider at Fermilab. We report on recent searches in the $B$ flavor sector, especially decays via flavor changing neutral current processes (FCNC), $B^0_{(s)} \to e^+\mu^-$ and $B^0_{s} to \mu^+ \mu^-$, at the Tevatron.
