Abstract

Production of ϕ mesons in small collision systems at \(\sqrt {{{s}_{{NN}}}} ~\) = 200 GeV has been studied in the PHENIX experiment at the RHIC. The ϕ meson nuclear modification factors have been investigated in the following collision systems: p + Al, p + Au, d + Au, and ³He + Au. The ϕ meson nuclear modification factors have been compared with the π⁰ meson nuclear modification factors in p + Al and ³He + Au collisions and the ϕ, π⁰ meson nuclear modification factors have been compared with the nuclear modification factors \({{\left( {p + \bar {p}} \right)} \mathord{\left/ {\vphantom {{\left( {p + \bar {p}} \right)} 2}} \right. \kern-0em} 2}\) in the p + Au collisions.

φ 小碰撞系统中的介子产生

摘要

在 RHIC 的 PHENIX 实验中研究了在\(\sqrt {{{s}_{{NN}}}} ~\) = 200 GeV的小型碰撞系统中产生 φ 介子。已在以下碰撞系统中研究了 φ 介子核修饰因子：p + Al、p + Au、d + Au 和³ He + Au。将 φ 介子核修饰因子与p + Al 和³ He + Au 碰撞中的 π 0 介子核修饰因子进行了比较，并将 φ, π ^0介子核修饰因子与核修饰因子进行了比较\({{\left( {p + \bar {p}} \right)} \mathord{\left/ {\vphantom {{\left( {p + \bar {p}} \right)} 2}} \right. \kern-0em} 2}\)在p + Au 碰撞中。
