Resummation of next to soft virtual terms for rapidity distributions of Drell-Yan and Higgs productions at the LHC |
|
Résumé |
We present a formalism that resums both threshold enhanced logarithms and their subleading
contributions to all orders in perturbative Quantum Chromodynamics for the rapidity distribution of any
colorless particle produced in hadron colliders. We achieve this by exploiting the factorization properties
and K+G equations satisfied by the soft and virtual parts of the cross section. We compute for the first
time, the resummed result in two dimensional Mellin space up to N3LL accuracy. Using various state-of-
the-art multi-loop and multi-leg results, we demonstrate the numerical impact of the resummed results up
to next-to-next-to leading order for the rapidity distributions of Drell-Yan and of the Higgs boson at the
Large Hadron Collider. We find that these threshold logs in the resummed result stabilise the predictions
against renormalization and factorization scale variations. |
