标题： On the breakdown of eikonal approximation and survival of Reggeization in presence of dimension-5 Higgs-gluon coupling

摘要： 我们考虑了在无限大顶夸克质量极限下，胶子与一个Regge化的胶子和希格斯玻色子相互作用的一圈有效顶点，该顶点由一个维数为5的不可重正化算符描述。 这个顶点进入了高能质子-质子碰撞中前向包含希格斯玻色子产生的微分截面计算中，可能伴随有后向喷注或标识的强子，在一个框架内，其中次领头对数被重新求和到所有阶。 这个有效顶点是从部分子-部分子碰撞中产生希格斯玻色子的两个到两个振幅的高能行为中提取出来的，并依赖于这些振幅的Regge形式的有效性。 我们发现，对于Regge极限，通常的eikonal近似（Gribov处方）和已知的区域展开技术导致振幅的一个不完整结果。 这种差异可以追溯到所涉及算符的不可重正化性质。 然而，精确QCD振幅的Regge极限在一圈时与Regge极交换形式一致，非平凡地支持了Regge化假设。 显示英文摘要

摘要： We consider the one-loop effective vertex for the interaction of a gluon with a Reggeized gluon and a Higgs boson in the infinite-top-mass limit, which is described by a dimension-5 non-renormalizable operator. This vertex enters the calculation of differential cross sections for the forward inclusive production of a Higgs boson in high-energy proton-proton collisions, possibly in association with a backward jet or identified hadron, in a framework where next-to-leading logarithms of the energy are resummed to all orders. The effective vertex is extracted from the high-energy behavior of two-to-two amplitudes for the Higgs production in parton-parton collisions and relies on the validity of the Regge form for these amplitudes. We find that the usual eikonal approximation (Gribov prescription) for the Regge limit and the known region-expansion technique in this limit lead to an incomplete result for the amplitude. The discrepancy is traced back to the non-renormalizable nature of the involved operator. However, the Regge limit of the exact QCD amplitude agrees with the Regge-pole exchange form at one loop, nontrivially supporting the Reggeization hypothesis.
