Measurements of B meson decay rates and CP violation asymmetries

TL;DR

This paper reviews the latest measurements of B meson decay rates and CP violation asymmetries, highlighting new experimental results that test the Standard Model and search for signs of New Physics.

Contribution

It presents the first measurements of several B meson decay modes and CP violation effects, including new evidence and the world's best measurement for specific decay channels.

Findings

Evidence of B0s to pipi decay

First search for CPV in B0s to phiphi decays

World's best measurement of BR (B0 to KK)

Abstract

Hadrons containing b-quarks represent a great opportunity to investigate the flavor sector of the Standard Model (SM) and to look for New Physics effects (NP). In this report we review the most up-to-date results on b-hadron decay rates and CP violating asymmetries: among other results, we report Branching Ratio (BR) and CP Violation (CPV) of B0, B0s and Lambda0b decay modes into pairs of charmless charged hadrons (pions, kaons and protons), the first search for CPV in B0s to phiphi decays and the first observation of bs to K0starK0star decay. Two new results from the CDF collaboration are reported: the first evidence of B0s to pipi decay and the world's best measurement of BR (B0 to KK).
