Abstract

Nuclear modification factors of φ mesons produced in Cu + Au and U + U collisions at cms energies of \(\sqrt {{{s}_{{NN}}}} \) = 200 and 192 GeV, respectively, are studied using data from the PHENIX experiment. The nuclear modification factors of φ mesons produced in U + U and Cu + Au collisions are compared to results obtained in Au + Au and Cu + Cu systems, and to those of the π⁰, η, K_S, and ω mesons produced in the same U + U and Cu + Au collisions.

摘要

研究了在Cus （+ sqrt {{{s} _ {{{NN}}}} \） cms能量分别为200和192 GeV的情况下在Cu + Au和U + U碰撞中产生的φ介子的核修饰因子。来自PHENIX实验的数据。以U + U和Cu + Au碰撞产生φ介子的核修正系数进行比较，以在Au中+ Au和铜+铜系统获得的结果，以及对与π的⁰，η，ķ_小号，并且在产生的ω介子相同的U + U和Cu + Au碰撞。
