Rare Radiative and Leptonic B Decays: Recent Results from BABAR and Belle

TL;DR

This paper reviews recent experimental results from BABAR and Belle on rare B meson decays involving photons and leptons, providing new limits and measurements that test the Standard Model predictions.

Contribution

It presents the latest preliminary limits and measurements on rare B decays from BABAR and Belle, enhancing the understanding of these processes and their consistency with the Standard Model.

Findings

No significant deviations from Standard Model predictions found.

New preliminary limits for B-->rho gamma and B-->omega gamma.

Updated measurements for B-->Xs l+l- and B-->K(*)l+l-.

Abstract

Recent BABAR and Belle results on rare B decays involving photons or lepton pairs are reviewed. New preliminary limits from both experiments for B-->rho gamma and B-->omega gamma, and from BABAR for B --> K nu nu and B --> tau nu are presented. Also summarized from the past year are Belle measurements of B-->Xs l+l- and B0-->K2(1430) gamma, preliminary BABAR measurements of B-->Xs gamma, and preliminary results from BABAR and Belle on B-->K(*)l+l-. No significant deviations from Standard Model predictions have yet been found.
