The Υ(5S) was discovered about 20 years ago in ee collisions at CLEO [1] and CUSB [2]. Its mass is (10865 ± 8) MeV, about 300 MeV higher than the Υ(4S) resonance, and its width of (110± 13) MeV is about five times larger than the Υ(4S) resonance. Its production cross-section was measured to be about 0.3 nb, about ten times lower than the Υ(4S) cross-section. Owing to its mass, the Υ(5S) can dec...
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 کاملB Meson Decays: Recent Results from Cleo
The CLEO Collaboration has extracted improved values of |Vcb| and |Vub| from measurements of exclusive and inclusive decays of B mesons. The measurement of B → D l ν at zero recoil combined with the predicted form factor FD∗(wmin) yields |Vcb|. The photon energy spectrum in b → s γ and the hadronic recoil mass spectrum in B → Xc l ν determine non-perturbative HQET parameters used with inclusive...
متن کاملEffects of final state interaction in B^+_c to D^0 K^+ decay
In this paper, the decay of Bc+ meson, which consists of two b and c heavy quarks, into the Do and K+ mesons was studied. Given that the experimental branching ratio for this decay was within the range of 3.75*10-5 to 11.16*10-5; it was decided to calculate the theoretical branching ratio by applying the final state interaction (FSI) through the T and cross-section channels. In this process, b...
متن کاملCP violation in B decays at the B A B AR experiment
During the first year of data taking, the 1999-2000 run, the BABAR detector at the SLAC PEP-II asymmetric collider has collected an integrated luminosity of 20.7 fb −1 corresponding to 22.7 million BB pairs at the Υ(4S) resonance. Using this data, we present the measurement of sin2β based on samples of B 0 → J/ψ K 0 S , B 0 → ψ(2S)K 0 S and B 0 → J/ψ K 0 L decays. Our measured value is sin2β = ...
متن کاملB Decays -measurements and Predictions * 1 Basic Methods on Upsilon-4s Resonance
Hadronic decays of B mesons are reviewed. First, masses of B mesons and observed patterns together with physics behind them are discussed. Then the effective Hamiltonian responsible for major decays is presented and its practical applications are discussed in the context of factorization. Various tests of factorization are then studied. For rare decays, the focus is placed on Kπ, ππ final state...
