First Synchrotron Injection Attempt into The SuperKEKB High Energy Ring

N. Iida, Y. Funakoshi, H. Kaji +17

A synchrotron injection scheme for the SuperKEKB electron high-energy ring (HER) was implemented and experimentally evaluated as the first attempt with a top-up injection during be…

Compensation of the Crossing Angle with Crab Cavities at KEKB

T. Abe, K. Akai, M. Akemoto +112

Crab cavities have been installed in the KEKB B--Factory rings to compensate the crossing angle at the collision point and thus increase luminosity. The beam operation with crab cr…

Evidence of B0 --> rho0 pi0

J. Dragic, T. Gershon

We present the first evidence of the decay B0 --> rho0 pi0, using 140fb^-1 of data collected at the Upsilon(4S) resonance with the Belle detector at the KEKB asymmetric e+e- collid…

Negative Momentum Compaction at KEKB

H. Ikeda, J. W. Flanagan, H. Fukuma +5

KEKB is a high luminosity e+e- collider for studying B mesons and has achieved the design luminosity of 1034cm-2s-1 in 2003. In order to get higher luminosity, we tested negative m…

Observation of a narrow charmonium-like state in exclusive B+ -> K+ pi+pi- J/psi decays

The Belle Collaboration, S. -K. Choi, S. L. Olsen

We report the observation of a narrow charmonium-like state produced in the exclusive decay process B+ -> K+ pi+pi- J/psi. This state, which decays into pi+pi- J/psi, has a mass of…
