Electroweak symmetry breaking modifies the hidden sector, generating a mass gap.

Predicted deviations in Higgs couplings could be observed at LHC and FCC energies.

Abstract

In the paper, we introduce the formalism to examine the impact of the hidden scalar sector to the conformal and the electroweak symmetries breaking. The novel approach to the scalar boson star (BS) naturalness is considered. The BS is presented by the local scalar field containing the Higgs boson field and the garland-like scalar dilaton fields of the conformal field theory. We show that taking into account the repulsive self-interactions and the flatness degree in the dark scalar sector prevents instability of the BS related to the black hole formation. We study in details how electroweak symmetry breaking affects the hidden sector by breaking its conformal symmetry and generating a mass gap to avoid the infra-red divergence. We apply our formalism to determine the modification of the Higgs quartic coupling away from its standard model (SM) value within the influence of the hidden sector. We have estimated the rate of the deviation from the SM with production of leptonic pairs due to decay of the dilaton and the dark photon. The latter is the subject of the dilaton decay first. The effect of new physics should be visible at the maximal energies of the LHC and the FCC.
