Triple Higgs coupling in the most general 2HDM at SM-like scenario
Ilya Ginzburg
TL;DR
This paper investigates the triple Higgs coupling in the most general Two-Higgs-Doublet Model (2HDM) under the SM-like scenario, finding that significant deviations from the Standard Model are unlikely unless certain exotic parameters are involved.
Contribution
It provides an analysis of the triple Higgs coupling in the general 2HDM, highlighting conditions under which deviations from the SM could be substantial.
Findings
Noticeable deviations are improbable at moderate parameter values.
Significant deviations require exotic measurable parameters.
The study constrains possible new physics effects in Higgs self-coupling.
Abstract
We consider the triple Higgs coupling for Higgs boson within the most general 2HDM. At moderate values of parameters of model, allowing by modern data, noticeable deviation of this coupling from its SM value is improbable. This deviation can be sizable only if some measurable parameters of the model are exotic.
