摘要：
We calculate the back-to-back correlation (BBC) functions of relativistic boson-antiboson pairs in high energy heavy ion collisions using the Monte Carlo method. The relativistic effects on the BBC functions of phi phi and K+K- pairs are investigated. The investigations indicate that the relativistic effects on the BBC functions of K+K- pairs with large momenta are significant, and the effect is sensitive to the particle freeze-out temperature.
