基于BCFW递归的高能因子分解放大器

Amplitudes for High Energy Factorization via BCFW recursion

Mirko Serino

摘要:

最近,BCFW在壳层递推关系的一个扩展,适用于计算具有离壳粒子的规范不变散射振幅,已被提出用于具有费米子的Yang-Mills理论。特别是,4点和5点振幅已经完全计算出来。这些结果是在高能因子化框架下研究强子对撞机上多部分子散射所需要的。

英文摘要:

Recently, an extension of the BCFW on-shell recursion relation suitable to compute gauge invariant scattering amplitudes with off-shell particles has been presented for Yang-Mills theories with fermions. In particular, 4- and 5-point amplitudes have been completely worked out. The results are needed for the study of multi-parton scattering at hadron colliders in the framework of High Energy Factorization (HEF).
