New Search for tau -> mu gamma and tau -> e gamma Decays at Belle

K. Hayasaka

We report on a search for the lepton flavor violating tau- -> mu- gamma and tau- -> e- gamma decays based on 535/fb of data accumulated at the Belle experiment. No signal is found…

Measurement of D0-D0bar mixing in D0->Ks pi+ pi- decays

L. M. Zhang

We report a measurement of D0-D0bar mixing in D0->Ks pi+ pi- decays using a time-dependent Dalitz plot analysis. We first assume CP conservation and subsequently allow for CP viola…

Time-Dependent CP Asymmetries in B0 -> Ks pi0 gamma transitions

The Belle Collaboration, Y. Ushiroda, K. Sumisawa

We report measurements of CP violation parameters in B0->Ks pi0 gamma transitions based on a data sample of 535x10^6 BB pairs collected with the Belle detector at the KEKB asymmetr…

Observation of a Near-threshold $D^{0} D ˉ^{0} π^{0}$ Enhancement in $B \to D^{0} D ˉ^{0} π^{0} K$ Decay

G. Gokhroo, G. Majumder

We report the first observation of a near-threshold enhancement in the $D^{0} D ˉ^{0} π^{0}$ system from $B \to D^{0} D ˉ^{0} π^{0} K$ decays using a 414 $fb^{- 1}$ data sample col…

Search for the h_c meson in B^+- ->h_c K^+-

F. Fang

We report a search for the $h_{c}$ meson via the decay chain $B^{\pm} \to h_{c} K^{\pm}$ , $\etac γ$ with $η_{c} \to K_{S}^{0} K^{\pm} π^{\mp}$ and $p p ˉ$ . No significant signals are obser…

Observation of a new charmonium state in double charmonium production in e+ e- annihilation at \sqrt{s} ~ 10.6 GeV

The Belle Collaboration, K. Abe

We report the first observation of a new charmonium state at a mass of $(3.943 \pm 0.006 \pm 0.006) G e V / c^{2}$ . This state, called X(3940), is observed in the process $e^+ e^- \to…
