饱和模型中平均横动量和粒子密度的快度和能量依赖性

Rapidity and energy dependence of average transverse momentum and particle density in saturation models

P. Brogueira, J. Dias de Deus, J. G. Milhano

摘要:

饱和模型--彩色玻璃凝聚和弦渗流--在平均横向动量<P_T>和快度粒子密度dn/dy之间强加了严格的关系。通过结合这种关系与一个适当的演化方程dn/dy,并施加能量动量守恒,我们得到一个公平的描述数据,一般AB碰撞(强子-强子,强子-核和核-核)在所有的快速和(高)能量。预测LHC。

英文摘要:

Saturation models -- colour glass condensate and string percolation -- impose a strict relation between the average transverse momentum, <P_T>, and the rapidity particle densities, dn/dy. By combining this relation with an appropriate evolution equation for dn/dy, and imposing energy-momentum conservation, we obtain a fair description of data, for generic AB collisions (hadron-hadron, hadron-nucleus and nucleus-nucleus) at all rapidities and (high) energies. Predictions are given for the LHC.
