In particle physics, B mesons are mesons composed of a bottom antiquark and either an up (B +), down (B 0), strange (B 0 s) or charm quark (B + c).The combination of a bottom antiquark and a top quark is not thought to be possible because of the top quark's short lifetime.

The combination of a bottom antiquark and a bottom quark is not a B meson, but rather bottomonium which is something. If the recently-discovered charmonium-like state X() is a loosely-bound S-wave molecule of the charm mesons D^0 \bar D^{*0} or D^{*0} \bar D^0, it can be.

For the study of the time dependent decay rate of B-meson, an interesting approach 35) was proposed. If the Upsilon(4S) is produced with substantial momentum, the B-meson’s momentum, P lab, also becomes large and is approximately one half of P Upsilon.

A detailed description is presented of the method used and the results obtained for measuring various decay widths of the B-mesons into baryon-antibaryon pairs: (i) into two light baryons: B → p p, Δ p,(ii) into one light and one charmed baryon: B → p Σ c, p Λ c,(iii) into two charmed baryons: B → Σ c, Ξ c, Λ c Ξ c,(iv) the decays induced by the b → s.

Excited B-meson states have. E.W. Varnes, (representing the BaBar collaboration), in Proceedings of the 31st International Conference on High Energy Physics Ichep3 B Meson Reconstruction. B mesons are reconstructed by combining tracks or photons to form candidates for the intermediate mesons in the decay, constraining these mesons to their known masses, and then combining them to form B candidates.

production in D+ s → π 0 transition in semileptonic decay. We also estimate the branching fraction of D+ s → π 0τ+ν τ, which is the only kinematically allowed semi-tauonic decay mode of the charmed meson, since the mass value of D+ s meson is just slightly above the threshold of π 0τ+ generation in the semi-tauonic decay.

The combination of experimental leptonic decay-rate measurements and theoretical decay-constant calculations enables the determination of several elements of the CKM matrix within the standard model.

These determinations are competitive with those obtained from semileptonic decays, and also complementary because they are sensitive to different. We review the present status for the determinations of the light and heavy quark masses, the light quark chiral condensate and the decay constants of light and heavy-light (pseudo)scalar mesons from QCD spectral sum rules (QSSR).

The f 1 () meson with mass ± MeV/c 2 and width ± MeV (full width at half maximum) was measured for the first time in photoproduction from a proton target using CLAS at Jefferson Lab. Differential cross sections were obtained via the ηπ + π - K + K 0 π - and K -K 0 π + decay channels from threshold up to a center-of-mass energy of GeV.

In the s, particle physicists began to realize that hadrons are not elementary particles but are made of particles called quarks.

(The name ‘quark’ was coined by the physicist Murray Gell-Mann, from a phrase in the James Joyce novel Finnegans Wake.)Initially, it was believed there were only three types of quarks, called up (u), down (d), and strange (s).

In an e + e − B factory, charmonium states can be produced through different mechanisms, e.g. direct production in e + e − annihilation, double charmonium production, and in B-meson production of J/ψ or ψ(2S) in association with a second charmonium states has been observed by both the B A B AR and the Belle experiments.

These processes provide an. For the study of the time dependent decay rate of B-meson, an interesting approach (35) was proposed. If the Upsilon(4S) is produced with substantial momentum, the B-meson's momentum, Plab, also becomes large and is approximately one half of [n].

Along with the running of Large Hadron Collider (LHC) located at CERN in Novembera large number of data samples of B c meson have been collected and some hadronic B c decay modes have been measured by the LHC experiments. In view of the special and important roles of Bc meson decays playing in the heavy flavor.

The book focuses on the reactions, properties, characteristics, and transformations of heavy flavors. The publication first offers information on flavor factories and monochromatization as the way to maximum luminosity B-factories, as well as design strategies and parameters, requirements, luminosity limitations, and B-factory with.
