Currently known as Squeezed or Back-to-Back Correlations (BBC), they should be present if the hadronic masses are modified in the hot and dense medium formed in high energy heavy ion collisions. Although well-established theoretically, such hadronic correlations have not yet been observed experimentally. In this phenomenological study we suggest a promising way to search for the BBC signal, by looking into the squeezed correlation function of phi phi and K^+ K^- pairs at RHIC energies, as function of the pair average momentum, K_{12}=(k_1+k_2)/2. The effects of in-medium mass-shift on the identical particle correlations (Hanbury-Brown & Twiss effect) are also discussed.", "revisions": [ { "version": "v1", "updated": "2009-01-08T02:55:14.000Z" } ], "analyses": { "subjects": [ "21.65.Jk", "21.65.Qr", "25.75.Gz", "25.75.-q" ], "keywords": [ "squeezed particle-antiparticle correlations", "high energy heavy ion collisions", "pair average momentum", "dense medium", "in-medium mass-shift" ], "tags": [ "journal article" ], "note": { "typesetting": "TeX", "pages": 6, "language": "en", "license": "arXiv", "status": "editable", "inspire": 810529 } } }
