超越Soft + Virtual
Going beyond Soft plus Virtual
摘要:
我们提出了一个形式主义,总结了软虚(SV)和下一个SV(NSV)的对角贡献包容性无色生产强子对撞机在微扰QCD的所有订单。利用因式分解定理、重整化群不变性和微扰结果的超越结构,证明了软共线函数的指数行为。这使我们能够预测某些SV和NSV条款的所有订单从低阶信息。我们还提出了一个积分表示的系数函数,这是适合梅林$N$ -空间重建。
英文摘要:
We present a formalism that sums up the soft-virtual (SV) and next-to-SV (NSV) diagonal contributions to inclusive colorless productions in hadron colliders to all orders in perturbative QCD. Using factorisation theorem, renormalisation group invariance and employing the transcendental structure of perturbative results, we show the exponential behavior of soft-collinear function. This allows us to predict certain SV and NSV terms to all orders from lower order information. We also present an integral representation for the coefficient functions which is suitable for Mellin $N$-space resummation.
