Ukrainian Journal of Physics| Резюме: | A new way to overcome the Λ hyperon selective suppression, which is known as the Λ-anomaly, has been suggested. In particular, the additional radius of a Λ hyperon is introduced into the model of hadron resonance gas with the multicomponent hard-core repulsion. The proposed approach allows one to describe the hadron multiplicity ratios measured at the AGS, SPS, and RHIC energies with the accuracy x2/dof = 52/55 ≃ 0.95. |
