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…

Time and Amplitude of Afterpulse Measured with a Large Size Photomultiplier Tube

K. J. Ma, W. G. Kang, J. K. Ahn +21

We have studied the afterpulse of a hemispherical photomultiplier tube for an upcoming reactor neutrino experiment. The timing, the amplitude, and the rate of the afterpulse for a…

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…

Sziklai's conjecture on the number of points of a plane curve over a finite field II

Masaaki Homma, Seon Jeong Kim

We settle the conjecture posed by Sziklai on the number of points of a plane curve over a finite field under the assumption that the curve is nonsingular.

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…
