摘要

我们计算了产生正向希格斯玻色子的影响因子的实际修正，保留了完全的顶质量依赖。我们证明了快速散度是BFKL分解所预测的散度，并在BFKL方案中进行了显式减法。我们证明了影响因子的ir结构是预期的，并且在无限顶质量近似中，恢复了先前已知的结果。我们还验证了当t通道Reggeon的横向动量趋于零时，影响因子消失，符合其规范不变定义，利用mt→∞扩展到次至次至前阶。

The next-to-leading order Higgs impact factor at physical top mass: the real corrections

We compute the real corrections to the impact factor for the production of a forward Higgs boson, retaining full top-mass dependence. We demonstrate that the rapidity divergence is the one predicted by the BFKL factorization and perform the explicit subtraction in the BFKL scheme. We show that the IR-structure of the impact factor is the expected one and that, in the infinite-top-mass approximation, the previously known result is recovered. We also verify that the impact factor vanishes when the transverse momenta of the t-channel Reggeon goes to zero, in agreement with its gauge-invariant definition, exploiting the m_t → ∞ expansion up to the next-to-next-to-leading order.

期刊介绍： The aim of the Journal of High Energy Physics (JHEP) is to ensure fast and efficient online publication tools to the scientific community, while keeping that community in charge of every aspect of the peer-review and publication process in order to ensure the highest quality standards in the journal. Consequently, the Advisory and Editorial Boards, composed of distinguished, active scientists in the field, jointly establish with the Scientific Director the journal''s scientific policy and ensure the scientific quality of accepted articles. JHEP presently encompasses the following areas of theoretical and experimental physics: Collider Physics Underground and Large Array Physics Quantum Field Theory Gauge Field Theories Symmetries String and Brane Theory General Relativity and Gravitation Supersymmetry Mathematical Methods of Physics Mostly Solvable Models Astroparticles Statistical Field Theories Mostly Weak Interactions Mostly Strong Interactions Quantum Field Theory (phenomenology) Strings and Branes Phenomenological Aspects of Supersymmetry Mostly Strong Interactions (phenomenology).
