The branching fraction of tau --> pi- K0S K0S (pi0) nu decays

J. P. Lees

We present a study of tau- --> pi- K0S K0S (pi0) nu and tau- --> K- K0S K0S (pi0) nu decays using a dataset of 430 million tau lepton pairs, corresponding to an integrated luminosi…

Observation of Time Reversal Violation in the B0 Meson System

The BABAR Collaboration, J. P. Lees, V. Poireau +364

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. The decays of entangled n…

Search for resonances decaying to eta_c pi+ pi- in two-photon interactions

The BABAR Collaboration, J. P. Lees, others

We report a study of the process gamma gamma -> X -> eta_c pi+ pi-, where X stands for one of the resonances chi_{c2}(1P), eta_c(2S), X(3872), X(3915), or chi_{c2}(2P). The analysi…

Evidence for an excess of B -> D(*) Tau Nu decays

The BaBar Collaboration

Based on the full BaBar data sample, we report improved measurements of the ratios R(D(*)) = B(B -> D(*) Tau Nu)/B(B -> D(*) l Nu), where l is either e or mu. These ratios are sens…

Study of Bbar --> Xu l nubar decays in BBbar events tagged by a fully reconstructed B-meson decay and determination of |V_{ub}|

The BABAR Collaboration

We report measurements of partial branching fractions for inclusive charmless semileptonic B decays Bbar --> Xu l nubar, and the determination of the CKM matrix element |V_{ub}|. T…

Searches for Rare or Forbidden Semileptonic Charm Decays

The BABAR Collaboration, J. P. Lees

We present searches for rare or forbidden charm decays of the form , where is a charm hadron (, , or ), i…
