CP violation in charm decays at Belle

B. R. Ko

We have searched for CP violation of charmed mesons in the decays $D \to K_{S}^{0} P$ , where $D$ denotes $D^{0}$ and $D_{(s)}^{+}$ , and $P$ denotes the pseudo-scalar mesons $π^{+}$ , $K^{+}$ , $π…

Measurement of CP violating asymmetries in B^0 -> K^+K^- K^0_S decays with a time-dependent Dalitz approach

Belle Collaboration, Y. Nakahama, K. Sumisawa +133

We report a measurement of $C P$ violating asymmetries in $B^{0} (B^{0}) \to K^{+} K^{-} K_{S}^{0}$ decays with a time-dependent Dalitz approach. This analysis is based on a data samp…

Effect of nuclear interactions of neutral kaons on CP asymmetry measurements

B. R. Ko, E. Won, B. Golob +1

We examine the effect of the difference in nuclear interactions of $K^{0}$ and $K ˉ^{0}$ mesons on the measurement of CP asymmetry for experiments at $e^{+} e^{-}$ colliders - charm a…

Observation of B+ -> Dbar*0 tau+ nu_tau and Evidence for B+ -> Dbar^0 tau+ nu_tau at Belle

A. Bozek, M. Rozanska et al.

We present measurements of B+ -> Dbar*0 tau+ nu_tau and B+ -> Dbar^0 tau+ nu_tau decays in a data sample of 657 x 10^6 BBbar pairs collected with the Belle detector at the KEKB asy…

Observation of Bs->Ds()+Ds()- using e+e- collisions and a determination of the Bs-Bsbar width difference ΔΓ_s

S. Esen, A. J. Schwartz, I. Adachi +125

We have made the first observation of Bs->Ds(*)+Ds(*)- decays using 23.6 fb-1 of data recorded by the Belle experiment running on the Upsilon(5S) resonance. The branching fractions…

Search for Lepton Flavor Violating Tau Decays into Three Leptons with 719 Million Produced Tau+Tau- Pairs

K. Hayasaka, K. Inami, Y. Miyazaki

We present a search for lepton-flavor-violating tau decays into three leptons (electrons or muons) using 782 fb^-1 of data collected with the Belle detector at the KEKB asymmetric-…

Search for CP violation in the decays $D_{(s)}^{+} \to K_{S}^{0} π^{+}$ and $D_{(s)}^{+} \to K_{S}^{0} K^{+}$

B. R. Ko, E. Won

We have searched for CP violation in the charmed meson decays $D_{(s)}^{+} \to K_{S}^{0} π^{+}$ and $D_{(s)}^{+} \to K_{S}^{0} K^{+}$ using 673 fb $^{- 1}$ of data collected with the Belle detector…
