A novel type of quantum mechanical correlations, hypothesized in the 1990's, the (squeezed) back-to-back correlations, was predicted to appear in heavy ion collisions among particle-antiparticle (eg. π+π-, K+K-, pp̄) pairs, if their in-medium masses are different from the vacuum values. Observation of this correlation would provide new insight in the freeze-out dynamics of the created matter. The latest status of the PHENIX measurement, comprising the first measurement of this new effect, is presented.
