摘要
大型强子对撞机 (LHC)能探测到核子中很小x的动力学区域 .在此动力学区域部分子的密度很大 ,根据高扭度修正过的AP演化方程 (MDAP方程 ) ,分析了此区域的部分子饱和问题 .发现在LHC能区不会出现饱和现象 ,但部分子分布会由于高扭度效应而明显被抑制 ,出现部分饱和现象 .根据MDAP演化方程 。
At Large Hadron-Hadron Collider(LHC), the structure of nucleon at much small x region can be revealed. With the high twist modified AP evolution equation (MDAP equation), the saturation problem of partons at LHC energies is analyzed. It is found that the parton distribution will not be saturated in this region, instead, due to the high twist effects, the parton distribution is obviously suppressed and partial saturation appears. With the MDAP equation, parton distributions at LHC energies are calculated.
