$qq'$后角散射中的正则化问题

Issues of Reggeization in $qq'$ Back-Angle Scattering

M. V. Bondarenco

摘要:

在不使用积分方程的情况下,重新推导了高能$qq'$后向散射DLLA的Kirschner-Lipatov结果。本文证明了数值发散积分中变量间的部分不等式是无关紧要的。讨论了后向散射条件下的光锥波函数解释。在价夸克模型中,强子-强子散射的正则化应该从$s_{hh}=50 GeV^2$开始充分显现。

英文摘要:

The Kirschner-Lipatov result for the DLLA of high-energy $qq'$ backward scattering is re-derived without the use of integral equations. It is shown that part of the inequalities between the variables in the logarithmically-divergent integrals is inconsequential. The light-cone wave-function interpretation under the conditions of backward scattering is discussed. It is argued that for hadron-hadron scattering in the valence-quark model the reggeization should manifest itself at full strength starting from $s_{hh}=50 GeV^2$.
