Contribution

It reviews how Higgs coupling analyses can indirectly test and constrain new physics scenarios beyond current collider capabilities.

Findings

Higgs coupling measurements can probe NP scales beyond current collider reach.

Various beyond Standard Model scenarios are systematically reviewed.

Precise Higgs property investigations are crucial for future NP discoveries.

Abstract

In view of the absence of any direct sign of New Physics (NP) at the LHC, the precise investigation of the Higgs properties becomes more and more important in our quest for physics beyond the Standard Model (SM). Coupling measurements play here an important role and not only complement the reach of the LHC but, depending on the physics scenarios, also allow for tests of NP scales beyond the ones accessible at present colliders. In this context, various representative scenarios beyond the SM will be reviewed.
