Measurement of the inclusive semileptonic branching fraction at Belle

Belle Collaboration, C. Oswald, P. Urquijo +172

We report a measurement of the inclusive semileptonic branching fraction in a data sample collected near the resonance with the Belle detector at the…

Search for CP Violation in the Decay

B. R. Ko, E. Won, I. Adachi +142

We search for CP violation in the decay using a data sample with an integrated luminosity of 977 fb collected with the Belle detector at the KEKB…

Study of B^0 -> rho^0 rho^0 decays, implications for the CKM angle phi_2 and search for other B^0 decay modes with a four-pion final state

The Belle Collaboration, P. Vanhoefer, J. Dalseno +171

We present a study of the branching fraction of the decay B^0->rho0rho0 and the fraction of longitudinally polarized rho0 mesons in this decay. The results are obtained from the fi…

Revisiting the gravitino dark matter and baryon asymmetry from Q-ball decay in gauge mediation

Shinta Kasuya, Masahiro Kawasaki, Masaki Yamada

We reinvestigate the scenario that the amount of the baryons and the gravitino dark matter is naturally explained by the decay of the Q balls in the gauge-mediated SUSY breaking. E…

Observation of ψ(4040) and ψ(4160) decay into ηJ/ψ

Belle Collaboration, X. L. Wang, Y. L. Han +126

The cross section for e^+e^- \to ηJ/ψbetween \sqrt{s}=3.8 GeV/c^2 and 5.3 GeV/c^2 is measured via initial state radiation using 980 fb^{-1} of data on and around the Υ(nS)(n=1,2,3,…

Study of the Hadronic Transitions (2S)(1S) at Belle

Belle Collaboration, U. Tamponi, R. Mussa +131

We study the rare hadronic transitions and using a sample of 158 decays collected with the Belle detecto…
