Experimental constraints on the spin and parity of the Z(4430)+
Belle Collaboration, K. Chilikin, R. Mizuk +188
We perform a full amplitude analysis of B0 -> psi' K+ pi- decays, with psi' -> mu+ mu- or e+ e-, to constrain the spin and parity of the Z(4430)-. The J^P=1+ hypothesis is favored…
First Observation of Radiative B^0 -> ϕK^0 γDecays and Measurements of Their Time-Dependent CP Violation
H. Sahoo, T. E. Browder
We report the first observation of the radiative decay B^0 -> ϕK^0 γusing a data sample of 772 x 10^6 B B-bar pairs collected at the Υ(4S) resonance with the Belle detector at the…
Evidence for direct CP violation in the decay B->D(*)K, D->KsPi+Pi- and measurement of the CKM phase phi3
The Belle Collaboration, A. Poluektov, A. Bondar +1
We present a new measurement of the unitarity triangle angle phi3 using a Dalitz plot analysis of the KsPi+Pi- decay of the neutral D meson produced in B->D(*)K decays. The method…
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…
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…
