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 ...
(dashed) lines refer to the energy levels of non-interacting Bs π (B K¯ ) pairs the quark masses in the lQCD simulation are not yet physical, the non-interacting energy levels of the lQCD are slightly shifted upward compared to those calculated theoretically using physical meson masses....

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 ...
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 the K meson, in an anticipation that the experimentalists will shortly be able to measure it for q2 up to, say, 2.0 GeV2 also, as Dally et al...

An abundance of the strangeness that can be induced in a thermalized quark-gluon plasma (QGP) is considered as a signal of the QGP phase appearing in the intermediate state of ultra-relativistic heavy-ion collisions. As a quantitative characteristic of this signal we take the ratio R_{K^+...
