Information on precautionary site access restrictions to Fermilab's Batavia site in response to coronavirus/COVID-19
We continue to review all events currently planned for the next sixty days and organizers will be notified if their event must be canceled, postponed, or held remotely. Please, check back on Indico during this time for updates regarding your meeting specifics.
As DOE O 142.3A, Unclassified Foreign Visits and Assignments Program (FVA) applies not only to physical access to DOE sites, technologies, and equipment, but also information, all remote events hosted by Fermilab must comply with FVA requirements. This includes participant registration and agenda review. Please contact Melissa Ormond, FVA Manager, with any questions.

Haitao Li - Los Alamos - via BLUE JEANS - Higgs pair production in gluon-gluon fusion

Description
The Higgs boson pair production via gluon fusion at high-energy hadron colliders, such as the LHC, is vital in deciphering the Higgs potential and in pinning down the electroweak symmetry breaking mechanism. In this talk, I will present the NNNLO QCD calculations in the infinite top-quark mass limit and predictions for both the inclusive and differential cross-sections. At the inclusive level, the scale uncertainties are reduced by a factor of four compared with NNLO results. Given that the inclusion of the top-quark mass effects is essential for the phenomenological applications, we use several schemes to incorporate the NNNLO results in the infinite top-quark mass limit and the NLO results with full top-quark mass dependence and present theoretical predictions for the cross-sections. Our results provide one of the most precise theoretical inputs for the analyses of the Higgs boson pair events
