    "abstract": "Back-to-Back Correlations (BBC) of particle-antiparticle pairs are predicted\nto appear if hot and dense hadronic matter is formed in high energy\nnucleus-nucleus collisions. The BBC correlations are related to in-medium\nmass-modification and squeezing of the quanta involved. The formalisms are\nanalogous in the bosonic (bBBC) and in the fermionic (fBBC) cases. Both the\nbBBC and the fBBC are positive and unlimited correlations of similar strength.\nFor testing the survival and the intensity of the effect in a more realistic\nsituation, we study the back-to-back correlations for mass-modification\noccurring in a finite sized, thermalized medium. For illustration, we consider\na non-relativistically expanding fireball with finite emission time. We show\nthat the BBC signal indeed survives the expansion and flow effects, with\nsufficient magnitude to be observed at RHIC.",
