Description
Femtoscopy analysis allows us to extract information about the
properties of source emitting particles of different types. From
"classical analysis" of two correlated pions one can calculated source
sizes, however, from the non-identical particle correlations, e.g.
pion-kaon femtoscopy, one can obtain information not only about source
size but about asymmetry in emission processes of pions and kaons as
well. Such asymmetry gives knowledge of which type of particles is
emitted first/second and/or from which region of the source. The studies
of non-identical particle femtoscopy for different collision energies
gives us the opportunity, to study how the source size and asymmetry in
particle emission depend on the initial conditions of the collision. In
this talk, we will present STAR results of pion-kaon femtoscopy at
mid-rapidity in Au+Au collisions from Beam Energy Scan program.
