TL;DR
This paper explores the potential existence of a hidden scalar particle with different CP properties from the Higgs boson, which could be detected through di-Higgs production at future colliders.
Contribution
It proposes a method to identify a new scalar with distinct CP properties behind the known Higgs boson via di-Higgs production analysis.
Findings
Potential to discover hidden scalars at future colliders
Distinct CP properties can be experimentally exposed
Enhances understanding of scalar sector extensions
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.
