Squeezed back-to-back correlations of K<sup>+</sup>K<sup>โ</sup>in d + Au collisions at =200 GeV and Au + Au collisions at = 62.4 GeV *
We investigate the squeezed back-to-back correlations (BBC) of $K^+$$K^-$, caused by the mass modification of the particle in the dense medium formed in d+Au collisions at $\sqrt{s_{NN}}=200$ GeV and Au+Au collisions at $\sqrt{s_{NN}}=62.4$ GeV. Considering some kaons may be not affected by the medium, we further study the BBC functions โฆ
