On the Sigma^0 --> Lambda^0 + gamma decay in the Effective quark model with chiral U(3)xU(3) symmetry
A. N. Ivanov, A. Ya. Berdnikov, Ya. A. Berdnikov +5
We analyse the angular distributions of the Sigma^0 --> Lambda^0 + gamma decay rate in the laboratory and in the rest frame of the Sigma^0 - hyperon in the dependence on baryon pol…
Polarization of Lambda^0 hyperons as a signature for the Quark-Gluon Plasma
A. Ya. Berdnikov, Ya. A. Berdnikov, A. N. Ivanov +5
The momentum distribution of Lambda^0 hyperons produced from the quark-gluon plasma (QGP) in ultra-relativistic heavy-ion collisions is calculated in dependence on their polarizati…
Singularities of ultra-relativistic expanding quark-gluon plasma within Quark-gluon transport theory
A. Ya. Berdnikov, Ya. A. Berdnikov, A. N. Ivanov +4
We follow Quark-gluon transport theory and analyse singularities of the ultra-relativistic and spherical expanding quark-gluon plasma. Within the linearized QCD oscillations and in…
On the K^+_- meson production from the quark-gluon plasma phase in ultra-relativistic heavy-ion collisions
A. Ya. Berdnikov, Ya. A. Berdnikov, A. N. Ivanov +3
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 ultr…
