# Theoretical implications of recent heavy flavour measurements at the LHC

## TL;DR

Recent LHC measurements of B meson decays show deviations from Standard Model predictions, prompting a review of experimental results, theoretical frameworks, and potential new physics explanations within existing constraints.

## Contribution

This paper provides a comprehensive review of recent heavy flavour measurements at the LHC, analyzing their implications for new physics beyond the Standard Model.

## Key findings

- Deviations observed in B meson decay observables challenge Standard Model predictions.
- Effective Hamiltonian descriptions help interpret experimental anomalies.
- Constraints from flavour physics and collider searches limit new physics models.

## Abstract

Recent measurements have revealed a number of intriguing deviations from the Standard Model predictions in $B$ meson decays, in particular in observables testing lepton flavour universality. We review their experimental status and theoretical description in terms of effective Hamiltonians. We also discuss possible new physics interpretations in terms of simplified models and summarise their status in view of the stringent constraints from flavour physics and high-$p_T$ collider searches.
