Strong interactions preserve an approximate isospin symmetry between up (u) and down (d) quarks, part of the more general flavor symmetry. In case K meson production, if this were exact, it would result in equal numbers charged (K+ K−) neutral (K0 $${\overline{K}}^{0}$$ ) mesons produced collisions isospin-symmetric atomic nuclei. Here, we report results on relative abundance over production argon scandium nuclei at a center-of-mass energy 11.9 GeV per nucleon pair. We find that K+ K−...

The $\pi^{\pm}$ measured increased precision compared to previously published results, while $K^{\pm}$ obtained first time. A strategy dealing dependence results on beam profile is proposed. purpose these measurements reduce...

We construct a simple model of heavy ion collisions, local in the impact parameter plane, and appropriate for SPS energy range. This can be regarded as new realization "fire-streak" approach, originally applied to studies lower nucleus-nucleus reactions. Starting from momentum conservation, we nicely describe broadening pion rapidity distribution when going central peripheral Pb+Pb collisions at $\sqrt{s_{NN}}$=17.3 GeV. The results our calculations are compared with experimental data....

The large and rapidly varying electric magnetic fields induced by the spectator systems moving at ultrarelativistic velocities induce a charge splitting of directed flow, $v_1$, positive negative pions in final state heavy ion collision. same effect results very sizeable distortion charged pion spectra as well ratios ($\pi^+/\pi^-$) emitted high values rapidity. Both phenomena are sensitive to actual distance between emission site system. This $d_E$ appears decrease with increasing rapidity...
