In this letter we present a solution to describe simultaneously the light isoscalar and isovector vector mesons in constituent quark models. In Ref. [1] the qq̄ spectrum was studied in a generalized constituent quark model constrained by the NN phenomenology and the baryon spectrum. An overall good fit to the available experimental data was obtained. A major problem of this description was the r...

The decay rates of QQ̄ mesons (Q ε c, b) are studied in the NRQCD formalism in terms of their short distance and long distance coefficients. The long distance coefficients are obtained through phenomenological potential model description of the mesons. The model parameters that reproduces the mass spectrum of the cc̄, bb̄ and cb̄ mesons are employed to study the decay widths of these mesons. We ext...

We provide nonperturbative fragmentation functions for B mesons, both at leading and next-to-leading order in the MS factorization scheme with five massless quark flavors. They are determined by fitting the fractional energy distribution of B mesons inclusively produced in e+e− annihilation at CERN LEP1. Theoretical predictions for the inclusive production of B mesons with high transverse momen...

We present measurements of the inclusive semileptonic branching fractions of charged and neutral B mesons using 20.6 fb−1 of data measured at the Υ (4S) with the BABAR detector. Events are tagged with a fully reconstructed hadronic decay of a B meson. The correlation between the flavor of the tag B meson and the electron charge allows the separation of prompt semileptonic B decays and cascade s...

We investigate the bound states of heavy mesons with finite masses to a classical soliton solution in the Skyrme model. For a given model Lagrangian we solve the equations of motion exactly so that the heavy vector mesons are treated on the same footing as the heavy pseudoscalar mesons. All the energy levels of higher grand spin states as well as the ground state are given over a wide range of ...

We report the first results of the nuclear modification factors and elliptic flow of the φ mesons measured by the PHENIX experiment at RHIC in high luminosity Au+Au collisions at √ sNN = 200 GeV. The nuclear modification factors RAA and RCP of the φ follow the same trend of suppression as π’s in Au+Au collisions. In d+Au collisions at √ sNN = 200 GeV, the φ mesons are not suppressed. The ellipt...

We discuss the decay of Bc mesons into two light mesons (π,K (∗), η(′), ρ, ω, φ). All these decay channels come from a single type of diagram, namely tree annihilation. This allows us to derive extremely simple SU(3) relations among these processes. The size of annihilation contributions is an important issue in B physics, and we provide two different estimates in the case of non-leptonic charm...

Recent experimental results on the transverse-momentum spectra (pT spectra) and the elliptic flow, v2, of non-photonic single electrons [K +04, L+04], whose main source at pT & 2GeV/c is the semileptonic decay of open-charm (and bottom) mesons, indicate that D mesons may have about the same v2 as light mesons. Calculations within a quark-coalescence model [GKR04] show that this can be explained...

Using phenomenological formulae, we can deduce the rest masses and intrinsic quantum numbers (I, S, C, B and Q) of quarks, baryons and mesons from only one unflavored elementary quark family ǫ. The deduced quantum numbers match experimental results exactly, and the deduced rest masses are 98.5% (or 97%) consistent with experimental results for baryons (or mesons). This paper predicts some quark...
