Beyond Standard Model searches through heavy flavors at BaBar
Marco Bomben (for the BaBar Collaboration)
TL;DR
This paper reviews recent searches for physics beyond the Standard Model conducted by the BaBar experiment, focusing on heavy flavor decays involving lepton-number violation, lepton-flavor violation, and CP violation.
Contribution
It presents new experimental results from BaBar on rare decay processes that could indicate new physics beyond the Standard Model.
Findings
No evidence of lepton-number violation in B^+ -> h^- l^+ l^+ decays
No observation of lepton-flavor violation in B^+/- -> h^+/- tau l decays
Measurements of CP violation in tau^- -> pi^- KS decays
Abstract
The BaBar experiment recorded 471 x 10^6 BBbar pairs at the Y(4S) resonance (corresponding to an integrated luminosity of 429 fb^-1). We present here a selection of recent results from the BaBar collaboration: search for lepton-number violation in the decay B^+ -> h^- l^+ l^+, search for lepton-flavor violation in B^+/- -> h^+/- tau l and CP-violation in tau^- -> pi^- KS (>= 0 pi^0) nu_tau.
