Running coupling constant of ten-flavor QCD with the Schrödinger functional method
Running coupling constant ten-flavor QCD Schrö dinger functional method
2011/1/14
Walking technicolor theory attempts to realize electroweak symmetry breaking as the spontaneous
chiral symmetry breakdown caused by the gauge dynamics with slowly varying gauge coupling constant and ...
We construct the transfer matrix for the ghost sector of partially quenched QCD. This transfer
matrix is not hermitian, but we show that it is still bounded. We thus expect that all euclidean correla...

微扰QCD演化过程中存在遮蔽效应的一个证据
纵向结构函数 遮蔽修正 QCD演化方程
2009/7/6
核子的纵向结构函数FL以及虚光子吸收的纵向和横向散射截面的比值RL在小X区域主要取决于胶子的分布函数.而胶子的初始分布函数的形式决定了在演化过程中是否要考虑遮蔽效应.利用新的动力学演化方程分析了FL和RL,发现在部分子演化过程中存在遮蔽现象.
