Description
A compilation of the experimental p+p data of neutral and charged kaon production has revealed a discrepancy between the observed K0 s yield and the the average number of produced charged kaons K0 s = (K+ +K−)/2. This widespread relation holds only for a colliding system that is an uniform population w.r. to the isospin (i.e. that consists of an equal number of all members of a given isospin multiplet). This is not the case for p+p collisions therefore one should not expect that it will describe the data accurately. A much better agreement is obtained with a model based on the quark structure of the participating hadrons (see Eur.Phys.J.C 83 (2023) 10, 928). Predictions of this model for p-A (see Eur.Phys.J.C 76 (2016) 2, 84) and A-A will also be presented.
