Although CP violation in the B-meson system has been well established by the B factories, there has been no direct observation of time-reversal violation in this system. Using 468 million B-Bbar pairs collected by the BABAR detector at SLAC, we measure T-violating parameters in the time evolution of neutral-B mesons by comparing the probabilities of B0 or anti-B0 transforming into definite CP...

The decays B -> tau nu, B -> D tau nu, and B -> D* tau nu are sensitive to physics beyond the standard model, in particular to contributions from charged Higgs bosons. The multiple-neutrino final states make studies of these decays particularly challenging and require reconstruction of the full event, which can be performed only at an electron-positron collider. We use the full BABAR data set...
