Systematic study of charged-pion and kaon femtoscopy in Au + Au collisions at sqrt(s_NN)=200 GeV
We present a systematic study of charged-pion and kaon interferometry in Au+Au collisions at sNN=200 GeV. The kaon mean source radii are found to be larger than pion radii in the outward and longitudinal directions for the same transverse mass ; this difference increases for more central collisions. The azimuthal-angle dependence of the radii was measured with respect to the second- order event plane and similar oscillations of the source radii were found for pions and kaons. Hydrodynamic models qualitatively describe the similar oscillations of the mean source radii for pions and kaons, but they do not fully describe the transverse-mass dependence of the oscillations.
