Nonperturbative scalar-meson resonances with open charm and beauty
نویسندگان
چکیده
We predict several new bound states and resonances for Bπ, BK, and BD S-wave elastic scattering, within the same model which was recently employed to explain the D sJ(2317) + meson. In the charm-nonstrange sector we find a (virtual ?) bound state close to the Bπ threshold, and moreover two nearby resonances of comparable width in the range 5.9 to 6.1 GeV. We obtain bound states B s0(5570) in bs̄ and B ∗ c0(6490) in b̄c, as well as resonances at higher energies. No JP = 0 states are found at 5.6 GeV (in b̄u/d), at 5.7 GeV (in bs̄), or at 6.1 GeV (in b̄c), where they are predicted from pure confinement.

Classification of the scalar mesons: a strange pole expedition into charm and beauty territory
The classification of scalar and vector mesons is reviewed within the framework of the Resonance-Spectrum Expansion (RSE). This method allows a simple and straightforward description of non-exotic meson-meson scattering, incorporating the effects of quark confinement and OZI-allowed decay in a fully nonperturbative way. Results for resonances and bound states are compared to experiment, on the ...

Charmed meson resonances with quantum numbers J P = 0 + and J P = 1 + are generated in terms of chiral coupled-channel dynamics. At leading order in the chiral expansion a parameter-free prediction is obtained for the scattering of Goldstone bosons off charmed pseudo-scalar and vector mesons. The recently announced narrow open charm states observed by the BABAR and CLEO collaborations are repro...

We will study open and hidden charm scalar meson resonances within two different models. The first one is a direct application of a chiral Lagrangian already used to study flavor symmetry breaking in Skyrme models. In another approach to the problem a SU(4) symmetric Lagrangian is built and the symmetry is broken down to SU(3) by identifying currents where heavy mesons are exchanged and suppres...

Production of final states containing open charm (c) and beauty (b) quarks at HERA is reviewed. Photoproduction (PHP) of the charm meson resonances D∗, D and Ds, as well as D∗ production in the deep inelastic scattering (DIS) regime, are measured and compared to QCD predictions. The excited charm mesons D 1(2420), D ∗0 2 (2460) and D ± s1(2536) have been observed and the rates of charm quarks h...
