Forward-backward and CP-violating asymmetries in rare B_{d,s}\to (V,\gamma) l^+l^- decays

TL;DR

This paper investigates forward-backward and CP-violating asymmetries in rare B meson decays to explore potential signs of physics beyond the Standard Model.

Contribution

It provides a detailed analysis of asymmetries in specific rare B decays and assesses their sensitivity to new physics extensions.

Findings

Asymmetries show potential to distinguish Standard Model from new physics scenarios.

Time-dependent and independent asymmetries offer complementary probes.

Results suggest certain asymmetries are highly sensitive to model extensions.

Abstract

We study the forward-backward and the CP-violating asymmetries (both time-independent and time-dependent) in rare semileptonic $B_d\to\rho^0 l^+l^-$, $B_s\to\phi l^+l^-$, and radiative leptonic $B_{d,s}\to \gamma l^+l^-$ decays and investigate the sensitivity of these asymmetries to the extensions of the Standard model.
