BaBar results on lepton universality and lepton and baryon number conservation

摘要

We present recent BABAR results on lepton universality in decays of the γ(2S) and γ(3S), and lepton-flavor violation and lepton-number violation in semileptonic charm hadron decays, and lepton-number and baryon-number conservation in B, and charm decays. No violations of these observed quantities are observed and improved or new upper limits are calculated on the respective branching fractions.
