摘要

We derive the formulas for calculating the squeezed back-to-back correlation (SBBC) between a boson and antiboson with nonzero width produced in relativistic heavy-ion collisions. The SBBCs of D-0 and phi mesons with finite in-medium widths are studied. We find that the finite width can change the pattern of the SBBC function of D-0(D) over bar (0) with respect to mass. However, the SBBC function of phi phi is insensitive to the width. In the high-particle-momentum region, the SBBC function of phi phi increases with particle momentum rapidly and can exceed that of D-0(D) over bar (0) whether the width is nonzero or not.
