Search for Second-Class Currents in tau- -> omega.pi-.nu_tau

The BaBar Collaboration, Philip Clark

Research output: Contribution to journalArticlepeer-review


We report an analysis of tau- decaying into omega.pi-.nu_tau with omega -> pi+pi-pi0 using a data sample containing nearly 320 million tau pairs collected with the BABAR detector at the PEP-II B-Factory. We find no evidence for second-class currents and we set an upper limit of 0.69% at 90% confidence level for the fraction of second-class currents in this decay mode.
