Description

We present a framework that resums the threshold enhanced large logarithms to all orders in perturbative theory for inclusive processes such as the production of a pair of leptons in Drell-Yan and of Higgs boson in gluon fusion as well as in bottom quark annihilation at the hadron colliders. These large logarithms are comprises of distributions log⁡^i (1−z)/(1−z) resulting from soft plus virtual (SV) and logarithms of the kind log⁡^i(1−z) from next to SV (NSV) contributions. We use collinear factorisation and renormalisation group invariance as the building blocks to achieve this. Using the integral representation of our all order $z$ space result, we show how the NSV contributions of the form log⁡^i(N)/N can be resummed in Mellin space. Reference : [hep-ph/2006.06726]
