We present a reliable estimate on the production rate of Bc mesons in 1S and 2S states in the large transverse momentum region at hadronic colliders using heavy quark fragmentation functions derived within the framework of perturbative QCD. We also present the transverse momentum distribution for the Bc mesons. The production rate is large enough for the Bc mesons to be identified at the Tevatr...

Neutral orbitally excited P-wave charm mesons have been reconstructed in the D * ± π ∓ final state and the charm-strange meson D ± s1 (2536) was found in the D * ± K 0 s final state. A search for radially excited charm mesons in the D * ± π + π − final state has also been performed. A search for a charm pentaquark state near 3.1 GeV was made in the decay mode D * ± p ∓. Using more than 40,000 r...

Some aspects of B physics relevant for experiments in hadron colliders are discussed. These include the determination of parameters of the CKMMatrix and confirmation of its role in CP violation, studies of mixing of nonstrange and strange B mesons, lifetimes of hadrons containing b quarks, the use of “same-side” tagging of neutral B mesons via correlations with charged pions through fragmentati...

We consider the fidelity of vector meson dominance (VMD) assumption as an instrument for relating electromagnetic vector-meson production reaction $e + p \to e^\prime V p$ to purely hadronic process $V V+p$. Analyses photon vacuum polarisation and photon-quark vertex reveal that such a VMD Ansatz might be reasonable light vector-mesons. However, when vector-mesons are described by momentum-depe...

A chiral Lagrangian with SU(3) breaking and higher resonances is proposed. In this model, the SU(3) breaking structure in vector-pseudoscalar sector is realized with the decay constants of pseudoscalar mesons and the masses of vector mesons used as inputs. We examine whether the resulting SU(3) breaking effect in the charge radii of pseudoscalar mesons is consistent with the experimental facts....

We review recent experimental results onB meson decays. These include measurements of the inclusive production of charmed and non-charmed mesons and baryons, the reconstruction of a large number of exclusive hadronic final states with charmed mesons, the search for exclusive hadronic final states without charmed mesons, and the first observation of the decay B → Kγ which is described by an elec...

The properties of vector mesons in nuclear matter are discussed. Results for the momentum dependence of the ρ-meson self energy in matter due to ρN interactions are presented, and consequences for the production rate of e+e− pairs in hot and dense matter are discussed. I also examine the constraints imposed by elementary processes on the widths of ρ and ω mesons in nuclear matter, and conclude ...

The nonmesonic weak decay of L hypernuclei is studied in a shell model framework. A complete strangeness-changing weak LN→NN transition potential, based on one boson exchange, is constructed by including the exchange of the pseudoscalar mesons p , K , h as well as the vector mesons r ,v , and K*, whose weak-coupling constants are obtained from soft meson theorems and SU~6!w . General expression...

This article reviews the current status of experimental results obtained in the measurement of light vector mesons produced in proton-proton and heavy ion collisions at different energies. The review is focused on two phenomena related to the light vector mesons; the modification of the spectral shape in search of chiral symmetry restoration and suppression of the meson production in heavy ion ...

Model-independent description of nonleptonic decays charmed mesons is a challenging task due to large nonperturbative effects strong interactions on the transition amplitudes. We discuss equivalence two different flavor-$SU(3)$-based descriptions Cabibbo-favored non-leptonic two-pseudoscalars final states including $\eta$ and $\eta^\prime$ mesons.
