Implications of lepton nonuniversality in the beauty sector

TL;DR

This paper reviews deviations from lepton universality observed in B meson decays, discusses their implications, and explores a leptoquark model as a potential explanation beyond the Standard Model.

Contribution

It analyzes recent anomalies in lepton universality measurements and proposes a leptoquark model to explain these deviations.

Findings

Observed deviations suggest possible new physics beyond the Standard Model.

Leptoquark models can potentially accommodate the anomalies.

Implications for future experiments and model building are discussed.

Abstract

The phenomenon of CP violation in the standard model (SM) framework and the decay dynamics have been established from the data obtained from the B factories and so far we have not seen anything new. Nevertheless, there have been instances of deviations in many measured observables in the flavor sector, as far as the data and predictions are concerned. Here we will mention some deviations obtained in measurements related to lepton universality, as seen from the data, and try to understand their implications. To accommodate the observed data we will consider a leptoquark model, which seems to be one interesting model beyond the SM.
