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−...
Measurements of the $\pi^{\pm}$, $K^{\pm}$, and proton double differential yields emitted from surface 90-cm-long carbon target (T2K replica) were performed for incoming 31 GeV/c protons with NA61/SHINE spectrometer at CERN SPS using data collected during 2010 run. 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...
