摘要:

根据研究相对论重离子碰撞的 Color Glass Condensate(色玻璃凝聚)方法,碰撞的最早阶段是 glasma(胶子等离子体前身),由可作经典处理的高占据胶子场构成。我们利用固有时展开解析地研究 glasma 的各种性质。特别地,我们计算了 glasma 的能量–动量张量,由此得到能量密度、纵向和横向压强、集体流以及角动量。我们还通过计算碰撞能量损失和横动量展宽,研究了 glasma 在 jet quenching(喷注淬火)中的作用。

英文摘要:

According to the Color Glass Condensate approach to relativistic heavy-ion collisions, the earliest phase of the collision is a glasma which is made of highly populated gluon fields that can be treated classically. Using a proper time expansion we study analytically various properties of the glasma. In particular, we compute the glasma energy-momentum tensor which allows us to obtain the energy density, longitudinal and transverse pressure, collective flow, and angular momentum. We also study the role of the glasma in jet quenching by computing collisional energy loss and transverse momentum broadening.
