Study of $π^{0}$ pair production in single-tag two-photon collisions

The Belle Collaboration, M. Masuda, S. Uehara +177

We report a measurement of the differential cross section of $π^{0}$ pair production in single-tag two-photon collisions, $γ^{*} γ \to π^{0} π^{0}$ , in $e^{+} e^{-}$ scattering. The cross secti…

Measurement of $e^{+} e^{-} \to γ χ_{c J}$ via initial state radiation at Belle

Belle Collaboration, Y. L. Han, X. L. Wang +142

The process $e^{+} e^{-} \to γ χ_{c J}$ ( $J$ =1, 2) is studied via initial state radiation using 980 fb $^{- 1}$ of data at and around the $Υ (n S)$ ( $n$ =1, 2, 3, 4, 5) resonances collected wi…

First Observation of CP Violation in B0->D(*)CP h0 Decays by a Combined Time-Dependent Analysis of BaBar and Belle Data

The BaBar, Belle Collaborations, : +471

We report a measurement of the time-dependent CP asymmetry of B0->D(*)CP h0 decays, where the light neutral hadron h0 is a pi0, eta or omega meson, and the neutral D meson is recon…
