Measurement of the absolute branching fraction of the Ds+- meson

The Belle collaboration

The Ds+- -> K+-K-+pi+- absolute branching fraction is measured using e+e- -> Ds*+- Ds1-+(2536) events collected by the Belle detector at the KEKB e+e- asymmetric energy collider. U…

A novel type of proximity focusing RICH counter with multiple refractive index aerogel radiator

T. Iijima, S. Korpar, I. Adachi +19

A proximity focusing ring imaging Cherenkov detector, with the radiator consisting of two or more aerogel layers of different refractive indices, has been tested in 1-4 GeV/c pion…

Measurement of phi_3 with Dalitz Plot Analysis of B+- -> D K*+- Decay

K. Abe

We present a measurement of the unitarity triangle angle phi_3 using a Dalitz plot analysis of the three-body decay of the neutral D meson from the B+- -> D K*+- process. Using a 2…

Evidence for Direct CP Violation in B0 -> K+- pi-+ Decays

Y. Chao

We report evidence for direct CP violation in the decay B0 -> K+-pi-+ with 253/fb of data collected with the Belle detector at the KEKB e+e- collider. Using 275 million B B_bar pai…

Study of B0 -> rho+-pi-+ Time-dependent CP Violation at Belle

C. C. Wang

We present a time-dependent analysis of CP violation in B0 -> rho pi decays based on a 140 1/fb data sample collected at the Y(4S) resonance with the Belle detector at the KEKB asy…

Observation of B+ to Lambda Lambdabar K+

Y. -J. Lee, M. -Z. Wang

We report the first observation of the charmless hyperonic B decay, B^+ --> Lambda Lambdabar K^+, using a 140 fb^-1 data sample recorded at the Upsilon(4S) resonance with the Belle…
