横动量加宽与规范不变性

Transverse momentum broadening and gauge invariance

Antonio Vairo

摘要:

在软共线有效理论的框架下,给出了介质中高能共线夸克横动量展宽几率的规范不变定义,并由此给出了喷注猝灭参数$\hat{q}$的定义.

英文摘要:

In the framework of the soft-collinear effective theory, we present a gauge invariant definition of the transverse momentum broadening probability of a highly-energetic collinear quark in a medium and consequently of the jet quenching parameter $\hat{q}$.
