Interferometry radii for expanding hadron resonance gas

Abstract We discuss the influence of the different physical factors on the interferometry radii of thermalized sources in A+A collisions. They are, first, non-Gaussian form of Bose-Einstein correlation function for direct pions at small p t , second, influence of the resonances, third, modification of the Gamov correction method for large expanding systems, including, particularly, specific role of long-lived resonances η, η′. Our results are based on the conception of the lengths of homogeneity.
