Triple Higgs boson production and electroweak phase transition in the two-real-singlet model

Osama Karkout, Andreas Papaefstathiou, Marieke Postma +3

The production of three Higgs bosons at hadron colliders can be enhanced by a double-resonant effect in the ${\mathbb{Z}}_2$-symmetric two-real-singlet extension of the Standard Mode…
