论文摘要
通过使用现象学模型进行未整合的gluon分布，研究了质子 - 蛋白质碰撞中致密gluonic状态的动力学熵。相应的横向动量概率分布是根据速度评估的。动力学熵密度是在与大型强子对撞机上碰撞相关的速度范围内获得的。在初始速度$ y_0 $的情况下，计算密度系统的总熵密度是迅速发展$Δy= y-y_0 $的函数。研究了理论的不确定性，并与文献中的相关方法进行了比较。
The dynamical entropy of dense gluonic states in proton-proton collisions at high energies is studied by using phenomenological models for the unintegrated gluon distribution. The corresponding transverse momentum probability distributions are evaluated in terms of rapidity. The dynamical entropy density is obtained in the rapidity range relevant for the collisions at the Large Hadron Collider. The total entropy density for the dense system is computed as a function of the rapidity evolution $ΔY = Y-Y_0$ given an initial rapidity $Y_0$. The theoretical uncertainties are investigated and comparison with related approaches in literature is done.
