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

Padula, Sandra dos Santos; Socolowski Junior, Otavio


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 pairs at RHIC energies.
