高能重离子碰撞中玻色子-反玻色子对背靠背关联函数的相对论效应
Relativistic effects on the back-to-back correlation functions of boson-antiboson pairs in high energy heavy ion collisions
摘要:
用蒙特卡罗方法计算了高能重离子碰撞中相对论玻色子-反玻色子对的背靠背关联函数。研究了相对论效应对$ϕ\,ϕ$和$K^+K^-$电子对BBC函数的影响。研究表明,相对论效应对大动量$K^+K^-$对的BBC函数有显著影响,且对粒子冻结温度敏感。
英文摘要:
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 $ϕ\,ϕ$ 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.
