Rare b-hadron decays as probe of new physics

TL;DR

Rare b-hadron decays serve as a crucial indirect method to explore potential new physics beyond the Standard Model, especially given the lack of direct signals at the LHC.

Contribution

This review summarizes the current status of rare b-hadron decay studies as probes for new physics beyond the Standard Model.

Findings

Rare b-hadron decays challenge the Standard Model predictions.

Flavour physics provides a sensitive indirect search for high-scale new physics.

Current experimental results constrain many new physics models.

Abstract

The unexpected absence of unambiguous signals of New Physics at the TeV scale at the Large Hadron Collider puts today flavour physics at the forefront. In particular rare decays of b-hadrons represent a unique probe to challenge the Standard Model paradigm and test models of New Physics at a scale much higher than that accessible by direct searches. This article reviews the status of the field.
