Inclusive $B\to X_s\gamma$ and $B\to X_s\ell^+\ell^-$ at the B factories

TL;DR

This paper presents recent measurements of inclusive B meson decays to strange hadrons and leptons, including branching fractions, CP asymmetries, and the first forward-backward lepton asymmetry measurement, providing insights into flavor physics.

Contribution

It reports new experimental measurements of observables in inclusive B decays, notably the first measurement of the forward-backward lepton asymmetry in these processes.

Findings

Measured branching fractions for B→X_sγ and B→X_sℓ^+ℓ^-

Determined CP asymmetries in both decay channels

First measurement of the forward-backward lepton asymmetry

Abstract

I report here recent measurements of observables from the inclusive decays $B\to X_s\gamma$ and $B\to X_s\ell^+\ell^-$. Included are measurements of the branching fractions and CP asymmetries for both channels, as well as the forward-backward lepton asymmetry in inclusive $B\to X_s\ell^+\ell^-$ decays, which is the first measurement of this quantity.
