The Higgs of the Higgs and the diphoton channel

TL;DR

This paper explores models where a new resonance, possibly the 750 GeV diphoton excess, arises from scale-invariance breaking, addressing the Higgs hierarchy problem and offering dark matter candidates.

Contribution

It introduces models linking a new resonance to scale invariance breaking, connecting LHC signals with solutions to the Higgs hierarchy and vacuum stability issues.

Findings

Models can be extrapolated to the Planck scale

Resonance explains the 750 GeV diphoton excess

Provides dark matter candidates and stabilizes the vacuum

Abstract

LHC results do not confirm conventional natural solutions to the Higgs mass hierarchy problem, motivating alternative interpretations where a hierarchically small weak scale is generated from a dimension-less quantum dynamics. We propose weakly and strongly-coupled models where the field that breaks classical scale invariance giving mass to itself and to the Higgs is identified with a possible new resonance within the LHC reach. As an example, we identify such resonance with the 750 GeV diphoton excess recently reported by ATLAS and CMS. Such models can be extrapolated up to the Planck scale, provide Dark Matter candidates and eliminate the SM vacuum instability.
