Squeezed correlations of strange particle-antiparticles
Abstract
Squeezed correlations of hadron-antihadron pairs are predicted to appear if their masses are modified in the hot and dense medium formed in high energy heavy ion collisions. If discovered experimentally, they would be an unequivocal evidence of in-medium mass shift found by means of hadronic probes. We discuss a method proposed to search for this novel type of correlation, illustrating it by means of Ds-mesons with in-medium shifted masses. These particles are expected to be more easily detected and identified in future upgrades at RHIC.
