The authors search for B{sup 0} meson decays into two-body combinations of K{sup 0}, {eta}, {eta}', and {phi} mesons in 324 million B{bar B} pairs collected with the BABAR detector at the PEP-II asymmetric-energy e{sup +}e{sup -} collider at SLAC. They measure …

The photon spectrum in B -> X-s gamma decay, where X-s is any strange hadronic state, is studied using a data sample of 88.5x10(6) e(+)e(-)->Upsilon(4S)-> B(B) over bar decays collected by the BABAR experiment at the Stanford Linear Accelerator Center. The partial …

Measurement of the direct CP asymmetry in b -> s gamma decays RID C-5223-2009 RID C-5719-2008 RID D-1055-2009

B Aubert, R. Barate, D. Boutigny, F Couderc et autres

We describe a measurement of the direct CP asymmetry between inclusive b-->sgamma and (b) over bar -->(s) over bar gamma decays. This asymmetry is expected to be less than 0.01 in the standard model, but could be enhanced up to about 0.10 …

We determine the inclusive B-->X(c)lnu branching fraction, B-clnu, the Cabibbo-Kobayashi-Maskawa matrix element V-cb, and other heavy-quark parameters from a simultaneous fit to moments of the hadronic-mass and lepton-energy distributions in semileptonic B-meson decays, measured as a function of the lower limit on …

We present results on time-dependent CP asymmetries in neutral B decays to several CP eigenstates. The measurements use a data sample of about 88x10(6) Y(4S)-->B (B) over bar decays collected between 1999 and 2002 with the BABAR detector at the PEP-II asymmetric-energy …
