Kaonic Hanbury-Brown-Twiss radii at 200 GeV and 5.02 TeV

We use 3+1 dimensional quasiparticle anisotropic hydrodynamics (aHydroQP) to make predictions for kaon Hanbury-Brown-Twiss (HBT) radii in 200 GeV and 5.02 TeV heavy-ion collisions. Using previously determined aHydroQP parameters, we compute kaonic HBT radii and their ratios as a function of the mean transverse momentum of the pair kT. We first consider Au-Au collisions at 200 GeV, finding good agreement between aHydroQP predictions and experimental data up to kT≈0.8 GeV. We then present predictions for kaonic HBT radii and their ratios in 5.02 TeV Pb-Pb collisions. Our aHydroQP predictions do not exhibit a clear kT scaling of the pion and kaon source radii, however, an approximate transverse mass mT scaling is observed, particularly at 200 GeV.
