Description
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(SM) 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 mechanism. 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.
