Description

The hadron collider phase of the Future Circular Collider (FCC-hh) is a proton-proton collider operating at a center-of-mass energy of 80-100 TeV. It is one of the most ambitious projects planned for the rest of this century and offers ample opportunities in the hunt for new physics, both through its direct detection reach as well as through indirect evidence from precision measurements.
This contribution presents recent studies of the di-Higgs measurement in the $bb\gamma\gamma$ final state, carried out as part of the input to the European Strategy Update. The same final state is exploited both for a precise measurement of the Higgs trilinear coupling and for testing BSM models that include a new scalar resonance decaying into a Higgs boson pair. Both interpretations are key to establish the shape of the Higgs potential and to constrain how New Physics may deform it.
