Higgs Production at NNLL +NNLO using Rapidity Dependent Jet Vetoes. (arXiv:2003.04323v1 [hep-ph])

Shireen Gangal, Jonathan R. Gaunt, Frank J. Tackmann, Eleni Vryonidou
The rapidity-dependent jet veto observables and provide a tight jet veto at central rapidity, gradually transitioning to a loose veto at forward rapidities. They divide the phase space into exclusive jet bins in a different way to the traditional jet veto observable , and are advantageous to use under harsh pile-up conditions. We obtain predictions for the -jet gluon-fusion (ggF) Higgs cross section using both of these veto observables at NNLL NNLO, and compare these predictions to the prior state-of-the-art of NLL NLO. A significant reduction in perturbative uncertainty is observed going from NLL NLO to NNLL NNLO, with the NNLL NNLO predictions lying inside the uncertainty band of the NLL NLO predictions. We also investigate the relative sensitivities of ggF Higgs cross sections with , and jet vetoes to underlying event and hadronisation effects using an NLO+parton shower calculation. We find that the cross sections with and vetoes have a reduced sensitivity to underlying event and hadronisation effects compared to that with a veto.

Researcher displays publicly available abstracts and doesn’t host any full article content. If the content is open access, we will direct clicks from the abstracts to the publisher website and display the PDF copy on our platform. Clicks to view the full text will be directed to the publisher website, where only users with subscriptions or access through their institution are able to view the full article.
