Previous two-step potential model calculations for the pion form factor in the space-like region are now extended to include the form factor of K meson, in an anticipation that the experimentalists will shortly be able to measure it for q exp 2 up to say 2.0 GeV exp 2 also, as Dally ...

Based on an expanding pure not quark-gluon plasma rireball Which is createa by ultrarelativistic heavy-ion aollisions, considering the internal occupation number of particle, using relativistic hydrodynamic equation, we investigated the rate of s-quark and K~--meson production. It is shown that ...
5 as functions of the produced χcJ meson transverse momentum for s=7 and 13 TeV. We find that the difference between the merging scenarios becomes well pronounced at large transverse momenta pT(χcJ), while both scenarios A and B lead to close results for 3PJ[1] spectra in the region ...
The observed strange meson resonances are found to have a natural interpretation in terms of states predicted by the quark model. In particular, the mass splittings of the leading trajectory natural spin-parity strange meson states and the mass splittings between the spin-orbit triplet states are...

We use vector meson dominance to calculate non-perturbative contributions to the branching ratio of the rare decay [Math Processing Error]K±→π±νν¯ stemming from matrix elements involving up-quark loops. The importance of this observable as well as of K0→ π0l+l− and of the direc...
The process of K/sub s/ regeneration on nuclei in the color quark model is investigated. The process of K/sub s/ regeneration on nuclie at high energies picks out those configurations in the incident K meson which have a large radius. This leads to stronger absorbtion of K meson by ...
Quark-meson coupling model with constituent quarks: Exchange and pionic effect The binding energy of nuclear matter including exchange and pionic effects is calculated in a quark-meson coupling model with massive constituent quarks. A... E M.,Bracco,G.,... - 《Physics Letters B》 被引量: ...
