大N_c微扰QCD中的Pomeron环

Pomeron loops in the perturbative QCD with Large N_c

M. A. Braun

摘要:

最低阶的坡密子环计算的领先的共形重量与完全依赖的三重坡密子顶点的中间共形重量。该循环被发现是收敛的。它对坡密子格林函数的贡献已经开始占主导地位,在rapidities 10 $÷$ 15。由于三重坡密子顶点随共形权的增加而迅速下降,坡密子极点重整化被发现是相当小的。

英文摘要:

The lowest order pomeron loop is calculated for the leading conformal weight with full dependence of the triple pomeron vertex on intermediate conformal weights. The loop is found to be convergent. Its contribution to the pomeron Green function begins to dominate already at rapidities 10$÷$15. The pomeron pole renormalization is found to be quite small due to a rapid fall of the triple pomeron vertex with rising conformal weights.
