Observation of a charmonium-like enhancement in the gamma gamma --> omega J/psi process
The Belle Collaboration, S. Uehara
We report the results of a search for a charmonium-like state produced in the process gamma gamma --> omega J/psi in the 3.9-4.2 GeV/c^2 mass region. We observe a significant enhan…
First Measurement of Inclusive B -> X_s eta Decays
Belle Collaboration, K. Nishimura, T. E. Browder +140
We report a first measurement of inclusive B -> X_s eta decays, where X_s is a charmless state with unit strangeness. The measurement is based on a pseudo-inclusive reconstruction…
Search for Lepton Flavor and Lepton Number Violating tau Decays into a Lepton and Two Charged Mesons
Y. Miyazaki
We search for lepton flavor and lepton number violating tau decays into a lepton (ell = electron or muon) and two charged mesons (h,h' = pi^\pm or K^\pm), tau- -> ell-h+h'- and tau…
Measurement of the e+e- --> D0D*-pi+ cross section using initial-state radiation
Belle Collaboration, G. Pakhlova
We report measurements of the exclusive cross section for e+e- --> D0D*-pi+ as function of center-of-mass energy from the D0D*-pi+ threshold to 5.2 GeV with initial-state radiation…
Measurement of Inclusive Radiative B-meson Decays with a Photon Energy Threshold of 1.7 GeV
A. Limosani
Using 605/fb of data collected at the Upsilon(4S) resonance we present a measurement of the inclusive radiative B-meson decay channel, B to X_s gamma. For the lower photon energy t…
High-statistics study of ${\boldmath ηπ^0}$ production in two-photon collisions
S. Uehara
The differential cross section for the process has been measured in the kinematic range $0.84 \GeV < W < 4.0 \GeV$, , where and are the energ…
Measurement of in meson decays to the final state
The Belle Collaboration
We present a measurement of the - mixing parameter using a flavor-untagged sample of decays. The measurement is based on a 673…
Dalitz analysis of B --> K pi psi' decays and the Z(4430)+
R. Mizuk
From a Dalitz plot analysis of B --> K pi psi' decays, we find a signal for Z(4430)+ --> pi+ psi' with a mass M= (4443(+15-12)(+19-13))MeV/c^2, width Gamma= (107(+86-43)(+74-56))Me…
Measurement of the Differential Branching Fraction and Forward-Backword Asymmetry for B->K(*)l+l-
J. -T. Wei, P. Chang
We study B->K(*)l+l- decays (l=e,mu) based on a data sample of 657 million BB pairs collected with the Belle detector at the KEKB e+e- collider. We report the differential branchin…
Effects of radiation damage caused by proton irradiation on Multi-Pixel Photon Counters (MPPCs)
T. Matsumura, T. Matsubara, T. Hiraiwa +9
We have investigated the effects caused by proton-induced radiation damage on Multi-Pixel Photon Counter (MPPC), a pixelized photon detector developed by Hamamatsu Photonics. The l…
