Correlation function intercepts for $\tilde{\mu},q$-deformed Bose gas model implying effective accounting for interaction and compositeness of particles
Abstract
In the recently proposed two-parameter -deformed Bose gas model [Ukr. J. Phys. {\bf 58}, 1171 (2013), arXiv:1312.1573] aimed to take effectively into account both compositeness of particles and their interaction, the -deformed virial expansion of the equation of state (EOS) was obtained. In this paper we further explore the -deformation, namely the version of -Bose gas model involving deformed distributions and correlation functions. In the model, we explicitly derive the one- and two-particle deformed distribution functions and the intercept of two-particle momentum correlation function. The results are illustrated by plots, and the comparison with known experimental data on two-pion correlation function intercepts extracted in RHIC/STAR experiments is given.
