Two-Particle Correlations from the q-Boson Viewpoint

We propose and develop to some extent a novel approach, which allows us to effectively describe, for relativistic heavy-ion collisions, the empirically observed deviation from unity of the intercept $\lambda$ (i.e. the measured value corresponding to zero relative momentum ${\bf p}$ of two registered pions or kaons) of the two-particle correlation function C(p,K). The approach is based on the use of two versions of the so-called q-deformed oscillators and the corresponding picture of ideal gases of q-bosons. By these techniques the intercept $\lambda$ is put into direct correspondence with the deformation parameter q.
