Isospin-symmetry in $pp$ and $AA$ collisions
A. V. Guskov, G. I. Lykasov, A. I. Malakhov, A. A. Zaitsev
The hypothesis of a violation of isospin-symmetry in pp and AA collisions is discussed. We show that the ratio of charged-to-neutral kaon cross sections, $R_K~=~\frac{σ_{K^+}+σ_{K^-}}{2σ_{K^0_S}}$, calculated within the similarity approach, including the gluon transverse momentum dependence (TMD) at low QCD scales, and …
