关于重离子碰撞中强子相空间中的光前表面

On the light front surfaces in the phase space of hadrons in heavy-ion collisions

Rahul Ramachandran Nair

摘要:

在重离子碰撞中产生的强子相空间中,对应于光阵面变量常值的表面形成抛物面。本文用UrQMD事件发生器模拟了$\sqrt{s} = 200$ GeV的Au-Au碰撞,证明了由一定的波前变量定值所定义的抛物面将相空间中的粒子分成两组,使得横向动量的平方分布,属于其中之一的粒子的极角和光阵面变量可以用由质量相关温度参数化的玻尔兹曼分布来描述。

英文摘要:

Surfaces corresponding to the constant values of the light front variable forms paraboloids in the phase space of the inclusively produced hadrons in heavy-ion collisions. In this paper, it is demonstrated with the simulated Au-Au collisions at $\sqrt{s} = 200$ GeV using the UrQMD event generator that the paraboloidal surface defined by a certain constant value of the light front variable divides the particles in the phase space into two groups such that the distributions of the square of the transverse momentum, the polar angle and the light front variable of particles belonging to one among them can be described with the Boltzmann distribution parameterised by the mass-dependent temperature.
