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…
