The differential cross-section in squared momentum transfer of , , , , , , , , , and produced in high-energy virtual photon-proton (), photon-proton (), and proton-proton () collisions measured by the H1, ZEUS, and WA102 Collaborations is analyzed by the Monte Carlo calculations. In the calculations, the Erlang distribution, Tsallis distribution, and Hagedorn function are separately used to describe the transverse momentum spectra of the emitted particles. Our results show that the initial- and final-state temperatures increase from lower squared photon virtuality to a higher one and decrease with the increase of center-of-mass energy.

高能碰撞平方动量传递中微分截面发射源的初态和终态温度

差分横截面的平方动量传递 由 H1、ZEUS 和 WA102 合作测量的高能虚拟光子 - 质子 ( )、光子 - 质子 ( )和质子 - 质子 ( )碰撞产生的能量通过蒙特卡罗计算进行分析。在计算中,分别使用 Erlang 分布、Tsallis 分布和 Hagedorn 函数来描述发射粒子的横向动量谱。我们的结果表明,初始和最终状态温度从较低的光子虚拟平方增加到较高的平方,并随着质心能量的增加而降低。
