光锥QCD等离子体

Light-Cone QCD Plasma

H. J. Pirner, K. Reygers

摘要:

我们推导了质子-质子和核-核碰撞中产生的部分子的最大熵态。该状态的特征在于分布函数n(x,pT),其分别取决于光锥分数x和向前或向后粒子的横向动量pT。平均横向动量<pT>决定了最大熵分布的单个参数,最大熵分布受所有光锥动量分数之和为1的约束。总多重数与碰撞的洛伦兹收缩强子的横截面积有关。假设部分子-强子对偶性,我们可以将模型与RHIC和LHC的数据进行比较。

英文摘要:

We deduce the maximum-entropy state of partons created in proton-proton and nucleus-nucleus collisions. This state is characterized by a distribution function n(x,pT) depending on the light-cone fraction x and the transverse momentum pT of forward or backward particles, respectively. The mean transverse momentum <pT> determines the single parameter of the maximum entropy distribution which is constrained by the sum of all light-cone momentum fractions being unity. The total multiplicity is related to the transverse area of the colliding Lorentz-contracted hadrons. Assuming parton-hadron duality we can compare the model to data from RHIC and LHC.
