摘要:

首次将关联飞秒方法应用于强子碰撞中介子产生的运动学完整测量。从近η介子产生阈值的pp -> ppX反应数据导出了一个双质子关联函数。为了进行这种分析而发展的一种技术,可以分别为pp+ η和pp+ π介子系统的产生建立关联函数。两质子关联函数的ppeta的形状不同的PP(π介子),都没有表现出相反的结果确定的重离子碰撞包容性测量的峰结构。

英文摘要:

For the very first time, the correlation femtoscopy method is applied to a kinematically complete measurement of meson production in the collisions of hadrons. A two-proton correlation function was derived from the data for the pp -> ppX reaction, measured near the threshold of eta meson production. A technique developed for the purpose of this analysis permitted to establish the correlation function separately for the production of the pp+eta and of the pp+pions systems. The shape of the two-proton correlation function for the ppeta differs from that for the pp(pions) and both do not show a peak structure opposite to results determined for inclusive measurements of heavy ion collisions.
