    "abstract": "Pion and kaon correlations in relativistic nuclear collisions are studied in\nthe framework of boost-invariant, cylindrically symmetric hydrodynamics. It is\ninvestigated how the inverse widths of the two-particle correlation functions\nin out- and side-direction depend on the average transverse momentum of the\nparticle pair, the initial energy density, and the equation of state of the\nsystem. The QCD transition leads to a time delay in the expansion of the system\nand consequently to an enhancement of the ratio of inverse widths in out- and\nside-direction. This time-delay signal is found to be particularly strong for\nlarge average transverse momenta of order 1 GeV and initial energy densities\naccessible at RHIC. Neutral kaon pair correlation functions, which are not\ninfluenced by final state Coulomb effects and less contaminated by resonance\ndecays than pion correlation functions, seem to be the ideal tool to detect\nthis collective time-delay signature of the QCD transition.",
