DESCRIPTION:Speakers: Konstantin Mikhaylov (ITEP\, JINR)\nDue to quantum s
 tatistical effects and final-state interactions\, momentum correlations be
 tween two or more particles emitted with small relative velocities (or\, e
 quivalently\, small relative momenta in their center-of-mass system) provi
 de a sensitive tool for probing the spatiotemporal characteristics of part
 icle-production processes at femtometer scales (10^−15 m). Kaons are par
 ticularly valuable for studying Bose–Einstein correlations because they 
 are less affected by resonance decays than more abundantly produced pions 
 and\, therefore\, provide a more direct probe of the properties of the pri
 mary particle-emitting source created in high-energy collisions. Combined 
 with femtoscopic measurements of pions and protons\, kaon correlations als
 o offer important information about the collective dynamics and evolution 
 of  strongly interacting matter. We report on the results of the femtoscop
 ic analysis of Bose–Einstein correlations of charged kaons in p–⁠Pb 
 and Pb–Pb collisions at √sNN = 5.02 TeV with the ALICE detector. Both 
 measurements show that the extracted source radii increase with charged-pa
 rticle multiplicity and decrease with increasing pair transverse momentum.
   This behavior is characteristic of space–momentum correlations associa
 ted with collective expansion and can be described within hydrodynamic mod
 els. The time of maximum kaon emission is determined through a three-dimen
 sional femtoscopic analysis for both collision systems. The value obtained
  in p-Pb collisions is comparable to that observed in highly peripheral Pb
 –Pb collisions\, suggesting that the evolution of kaon emission is simil
 ar in p–Pb and peripheral Pb–Pb collisions. The EPOS-3 hadronic intera
 ction model reproduces the measured source sizes in p–Pb collisions reas
 onably well\, except for an underestimation of the source size in the most
  central collisions. For the Pb–Pb data\, the integrated hydrokinetic mo
 del provides a good description of the transverse-momentum dependence of t
 he source radii\, except for the outward component in the longitudinally c
 omoving system (LCMS).\n\nhttps://indico.particle.mephi.ru/event/626/contr
