高能分解的散射振幅

Scattering amplitudes for high-energy factorization

A. van Hameren

摘要:

给出了一个构造具有明显规范不变的树级散射振幅的处方,该处方具有一个或两个离壳层初态胶子,用于在终态中具有任意粒子的过程,这使得计算高效且易于自动化。这些散射振幅与共线因式分解之外的因式分解方案有关,共线因式分解方案允许进入部分子截面的胶子具有非零的横向动量分量。

英文摘要:

A prescription is presented to construct manifestly gauge invariant tree-level scattering amplitudes with one or two off-shell initial-state gluons for processes with arbitrary particles in the final state, which allows for calculations that are efficient and easy to automate. These scattering amplitudes are relevant for factorization schemes beyond collinear factorization that allow the gluons entering the partonic cross section to have non-vanishing transversal momentum components.
