论文摘要
使用多源热模型的框架，我们分析了高能在不同碰撞中产生的各种喷气机的实验横向动量光谱。考虑了两个能源，一个弹丸参与者夸克和一个目标参与者夸克。假定每个能源源（每个参与者夸克）有助于横向动量分布为TP样函数，即修订后的Tsallis-Pareto-type函数。两个参与者夸克对横向动量分布的贡献是两个类似TP的函数的卷积。该模型分布可用于拟合通过不同协作测量的实验光谱。然后获得相关参数，例如熵指数相关，有效温度和修订指数。这些参数的趋势对于理解高能量碰撞的特征很有用。
With the framework of the multi-source thermal model, we analyze the experimental transverse momentum spectra of various jets produced in different collisions at high energies. Two energy sources, a projectile participant quark and a target participant quark, are considered. Each energy source (each participant quark) is assumed to contribute to the transverse momentum distribution to be the TP-like function, i.e. a revised Tsallis--Pareto-type function. The contribution of the two participant quarks to the transverse momentum distribution is then the convolution of two TP-like functions. The model distribution can be used to fit the experimental spectra measured by different collaborations. The related parameters such as the entropy index-related, effective temperature, and revised index are then obtained. The trends of these parameters are useful to understand the characteristic of high energy collisions.
