DESCRIPTION:Speakers: Vitalii Okorokov (National Research Nuclear Universi
 ty "MEPhI")\nA multi-particle Bose–Einstein symmetrization can enhance t
 he emission of pions and as consequence can lead to the creation of pion l
 asers in strong interactions at high energies. Onset of the Bose–Einstei
 n condensation is driven by the critical space density of charged secondar
 y bosons which are mostly pions. The energy dependence of space pion densi
 ty at freeze-out and its critical value\, calculated from estimations for 
 volume of emission region and for total multiplicity\, is investigated for
  both the proton-proton and the nucleus-nucleus collisions. The space-time
  extent of emission region is derived with the help of Bose–Einstein cor
 relations of pion pairs produced in various collisions within the framewor
 k of three dimensional Gaussian model for the source. It is shown that the
  space density of charged particles is smaller than its critical value and
  Bose–Einstein condensation cannot be expected for secondary pions in pr
 oton-proton collisions at energies up to about 100 TeV or even higher. A m
 arked enhancement is observed for charged pion density in heavy ion collis
 ions with respect to the proton-proton ones at similar collision energies.
  Relation between the charged particle density and its critical value allo
 w the possibility of lasing behavior for secondary pions in nucleus-nucleu
 s collisions in multi-TeV energy domain.\n\nhttps://indico.particle.mephi.
