Two-particle correlations from the q-boson viewpoint

We propose and develop to some extent a novel approach, which allows to eff ectively describe, for relativistic heavy-ion collisions, the empirically o bserved deviation from unity of the intercept lambda (i.e. the measured val ue corresponding to zero relative momentum p of two registered identical pi ons or kaons) of the two-particle correlation function C(p, K). The approac h is based on the use of two versions of the so-called q-deformed oscillato rs and the corresponding picture of ideal gases of q-bosons. By these techn iques the intercept lambda is put into direct correspondence with the defor mation parameter q. For fixed deformation strength, the model predicts part icular dependence of the intercept lambda on the pion pair mean momentum K.
