Abstract: The information about dynamics of the collective expansion of the source created in heavy ion collisions can be extracted by using intensity interferometry in different regions of rapidity and transverse momentum (pt). The study of different factors affecting the pt-dependenceof the radii and the strength of the correlation is necessary and that is why we have studied the influence of the particle identification efficiency and the presence of the pions from resonance decays on (p+,p+) correlation function measured by ALICE experiment.
