Electroweak corrections to $g+g\to H_{l,h}$ and $H_{l,h}\to\gamma+\gamma$ in the Higgs-singlet extension of the Standard model
arXiv (Cornell University)(2022)
Abstract
We calculate the next-to-leading order electroweak corrections for Higgs-boson production in gluon fusion and the Higgs-boson decay into two photons or gluons in the real Higgs-singlet extension of the Standard model (HSESM). For the light Higgs-boson of the HSESM the electroweak corrections for these processes are of the same order of magnitude as in the Standard model. For the heavy Higgs-boson of the HSESM the electroweak corrections can become large depending on the considered scenario.
