Branching fractions and direct CP asymmetries of charmless decay modes at the Tevatron
We present new CDF results on the branching fractions and time-integrated direct CP asymmetries for B and B s decay modes into pairs of charmless charged hadrons (pion or kaon). The data set for this update amounts to 1 fb of p̄p collisions at √ s = 1.96 TeV. We report the first observation of the B s → K π mode and a measurement of its branching fraction and direct CP asymmetry. We also observe...

متن کاملA signal of new physics from measuring CP violation in B d , s → μ + μ −
We analyze the possibility of observing CP violating effects in B 0 d,s → µ + µ − decays in future B factory. The CP violating obervables are defined by taking into account the mixing of the neutral mesons, B 0 d,s and ¯ B 0 d,s. It is shown that in the approximation of | q p |=1 the CP violation vanishes in SM. In a 2HDM with CP violating phases and MSSM the CP asymmetries depend on the parame...
متن کامل1 CP violation in Bd,s → l + l −
The FCNC process B d,s → ll has been shown in recent years to be a powerful process to shed light on new physics beyond SM [1,2,3,4,5] especially for SUSY models which may enhance the decay amplitude by tan β [1,6,2,3], provided that tanβ is large (say, ≥ 20). It became more interesting recently after the Brookhaven National Laboratory (BNL) reported the 2σ excess of the muon anomalous magnetic...
متن کاملFirst observation of B0s→J/ψf0(980) decays
First observation of B 0 s → J /ψ f 0 (980) decays ✩ .LHCb Collaboration a r t i c l e i n f o a b s t r a c t Using data collected with the LHCb detector in proton–proton collisions at a centre-of-mass energy of 7 TeV, the hadronic decay B 0 s → J /ψ f 0 (980) is observed. This CP eigenstate mode could be used to measure mixing-induced CP violation in the B 0 s system. Using a fit to the π + π...
