DESCRIPTION:Speakers: Elena Rogochaya (JINR)\nFemtoscopy provides informat
 ion on size and dynamics of the system created in heavy-ion collisions. At
  ultra-relativistic energies\, such as those obtained at the LHC\, signifi
 cant production of pions and kaons enables femtoscopic measurements for th
 ese particles. In particular\, a decreasing dependence of system size on i
 ncreasing pair momentum and particle mass could be interpreted as an evide
 nce of the strong collective flow. Such phenomena are naturally modeled by
  hydrodynamics. We present calculations within the EPOS 3 hadronic interac
 tion model\, which is based on a (3+1)D viscous hydrodynamical evolution a
 nd employs the UrQMD cascade to describe the hadronic phase\, correspondin
 g to Pb-Pb collisions at $\\sqrt{s_{\\rm NN}} =2.76$ TeV. The model femtos
 copic radii are considered as a function of pair transverse momentum and c
 ollision centrality and compared with the experimental data provided by th
 e ALICE collaboration. The obtained results show the importance of the had
 ronic rescattering phase at LHC energies.\n\nhttps://indico.particle.mephi
