1001.0126 (Sandra S. Padula et al.)

Searching for squeezed particle-antiparticle correlations in high energy
heavy ion collisions
   [PDF]

Sandra S. Padula, O. Socolowski Jr
Squeezed correlations of particle-antiparticle pairs were predicted to exist if the hadron masses were modified in the hot and dense medium formed in high energy heavy ion collisions. Although well-established theoretically, they have not yet been observed experimentally. We suggest here a clear method to search for such signal, by analyzing the squeezed correlation functions in terms of measurable quantities. We illustrate this suggestion for simulated phi-phi pairs at RHIC energies.
