Charged Higgs pair production and neutrino effects on the triple Higgs coupling
Julien Baglio
TL;DR
This paper explores how beyond Standard Model physics, specifically charged Higgs pairs and heavy neutrinos, influence Higgs pair production and the triple Higgs coupling at the LHC.
Contribution
It reviews charged Higgs pair production in Two-Higgs-Doublet models and analyzes heavy neutrino effects on the triple Higgs coupling.
Findings
Charged Higgs pair production is significant in Two-Higgs-Doublet models.
Heavy neutrinos induce one-loop corrections to the triple Higgs coupling.
BSM physics can notably alter Higgs pair production processes.
Abstract
Higgs pair production is one of the primary goals of the LHC program. Investigating the effects beyond the Standard Model (BSM) is then of high interest. Two cases are presented to exemplify the impact of BSM physics on Higgs pair production and on the triple Higgs coupling: first a review on charged Higgs pair production mostly in the context of Two-Higgs-Doublet of type II and in particular the Minimal Supersymmetric SM, second a study of the one-loop effects of a heavy neutrino on the triple Higgs coupling.
