Threshold resummation of rapidity distribution for Higgs production at NNLO+NNLL

Prasanna Kumar Dhani


With the increasing accurate measurements of various observables at the Large Hadron Collider,​ ​precise theoretical predictions are of paramount importance which will help not only to understand
Standard Model better but also to constrain various observables beyond the SM scenarios. The inclusive​ ​production of colorless particles, as in Drell-Yan process and the Higgs production in the final state has​ ​been studied both in fixed order as well as in resummed frameworks. The perturbative predictions for​ ​differential observables like rapidity, transverse momentum are underway. In my talk, I will present​ ​our recent work on​ ​resummation of rapidity distributions for the Higgs production via gluon fusion.​ ​We provide an all order prediction for the resummed cross section in two dimensional Mellin space.​ ​We find significant reduction in scale uncertainties due to unphysical scales at NNLO + NNLL.
