Rare B Decays at BaBar
Fernando Palombo (for the BABAR Collaboration)
TL;DR
This paper reports recent BaBar measurements of rare B decays, including asymmetries and branching fractions, and presents a search for a specific decay mode, contributing to understanding flavor physics and CP violation.
Contribution
It provides new experimental data on rare B decay modes and asymmetries, enhancing the understanding of flavor physics beyond previous measurements.
Findings
Measured rate asymmetries in B to K(*) l+ l- and K+ pi- decays.
Determined branching fractions for B to l+ nu_l, K_1(1270)+ pi-, and K_1(1400)+ pi- decays.
Conducted a search for B+ to K0_S K0_S pi+ decay mode.
Abstract
I present some of the most recent BaBar measurements for rare B decays. These include rate asymmetries in the B decays to K(*) l+ l- and K+ pi- and branching fractions in the B decays to l+ nu_l, K_1(1270)+ pi- and K_1(1400)+ pi-. I also report a search for the B+ decay to K0_S K0_S pi+.
