We present a measurement of the Standard Model CP violation parameter sin 2φ1 based on a 29.1 fb −1 data sample collected at the Υ(4S) resonance with the Belle detector at the KEKB asymmetric-energy e+e− collider. One neutral B meson is fully reconstructed as a J/ψKS , ψ(2S)KS , χc1KS , ηcKS , J/ψKL or J/ψK ∗0 decay and the flavor of the accompanying B meson is identified from its decay product...
متن کاملMeson B fragmentation function with consideration of mass corrections
Study of B meson (meson with the bottom quark flavor) in Large Hadron Collider (LHC) is of special importance so that the detector LHCb is devoted to investigate these types of mesons. For this reason, in this paper we will study the production process of this meson in a phenomenological approach using the experimental data from electron-positron annihilation. In this regards, we shall calculat...

متن کاملNew Time Distributions of D-D̄ or B-B̄ Mixing and CP Violation
The formulae for D0-D̄0 or B0-B̄0 mixing and CP violation at the τ -charm or Bmeson factories are derived, for the case that only the decay-time distribution of one D or B meson is to be measured. In particular, we point out a new possibility to determine the D0-D̄0 mixing rate in semileptonic D decays at the Ψ(4.14) resonance; and show that both direct and indirect CP asymmetries can be measured ...
متن کاملTesting Time Reversal Invariance with Cold Neutrons
CP violation is implemented in the Standard Model (SM) of particle physics via a non-trivial phase in the Cabbibo-Kobayashi-Maskava matrix 1. Dedicated experiments and facilities have been built to check the predictions of the SM for CP violation, e.g. in the Kaon or the B meson sectors. Up to now, no significant deviations have been found. However, the CP violation implemented in the SM is ins...
