Quark ModelTwo-Body ProblemWeak Hadronic DecayIt is shown that certain puzzling features indicated by recent data on D-meson decays into pseudoscalar mesons can be understood in a non-relativistic quark model used in conjunction with current algebra. (author)Riazuddin...

interactions with the QGP constituents, – 27 – which impart the flow of the medium to the heavy quarks, and from the hadronisation via recombination, which enhances the charm-hadron v2 with respect to the one of the charm quark because the D meson picks up the v2 of the light quark....
Quark-exchange versus meson-exchange in d(e,e′p)Δ We demonstrate that the meson-exchange contribution to D(e,e'p)Delta(T{sub p} {approx} 0.7-1 GeV and being at rest) is small compared to the six-quark cont... Leonid Ya. Glozman,A Faessler - 《Physics Letters B》 被引量: 10...
We demonstrate that the meson-exchange contribution to d(e,e′p)Δ (Ep ∼ 0.7 − 1 GeV and Δ being at rest) is small compared to the six-quark contribution. The cross-section is large enough to be measured at CEBAF. This means that through this reaction we could observe and study...
The new feature of our calculation is that we separately determine the nonperturbative and the $O(\\alpha_s)$ corrections to the longitudinal ($L$) and transverse ($T$) pieces of the spin 1 $D_s^{\\ast -}$ meson. The longitudinal/transverse composition of the $D_s^{\\ast -}$ ...

Possible rescattering effects are represented by the a, b meson pair. Decays of D mesons proceed through the weak decay of the charm quark together with the hadronisation forming the final-state mesons, including rescattering processes, before reaching the detector. Scattering amplitudes are, ...
The quark-meson coupling (QMC) model for nuclear matter, which describes nuclear matter as non-overlapping MIT bags bound by the self-consistent exchange of scalar and vector mesons is modified by the introduction of a density dependent bag constant. The density dependence of the bag constant is...
