Exposing new scalars hiding behind the Higgs boson
arXiv:2212.05390 · doi:10.1103/PhysRevD.107.055040
Abstract
It is possible that there is another scalar hiding behind the known 125 GeV Higgs boson. If the hidden scalar exhibits a CP property different from the Higgs boson, it can be exposed in the di-Higgs production at the high-luminosity large hadron collider and future colliders.
