We provide, within the hydrokinetic model, a detailed investigation of kaon
interferometry in Pb+Pb collisions at LHC energy (sNNββ=2.76
TeV). Predictions are presented for 1D interferometry radii of KS0βKS0β and
KΒ±KΒ± pairs as well as for 3D femtoscopy scales in out, side and
long directions. The results are compared with existing pion interferometry
radii. We also make predictions for full LHC energy.Comment: 12 pages, 6 figure
