Obtaining femtoscopy results in models with resonances
We present femtoscopic results from models in which the resonance contribution is taken into account. The Therminator program, which implements a single freeze-out model and takes into account propagation and decay of all known resonances, was used. We test methods of determining the femtoscopic size of the system, or the ''HBT radii''. We show that the best one is the two-particle method combined with the exact calculation of the two-pion wave function including the wave-function symmetrization and Coulomb effects. We compare it to other methods and comment on their validity and applicability.
