Achievement of 200,000 hours of operation at KEK 7-GeV electron 4-GeV positron injector linac

Kazuro Furukawa, Mitsuo Akemoto, Dai Arakawa +39

KEK electron positron injector LINAC initiated the injection operation into Photon Factory (PF) light source in 1982. Since then for 39 years, it has served for multiple projects,…

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 the Purely Leptonic Decay B- --> tau- nu_tau-bar

K. Ikado

We present the first evidence of the decay B- --> tau- nu_tau-bar using 414 fb^-1 of data collected at the Upsilon(4S) resonance with the Belle detector at the KEKB asymmetric-ener…

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…

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…

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…
