Evidence of the true Higgs boson HT at the LHC Run 2

Abstract

The aim of this paper is to compare the recent LHC data at [Formula: see text] =13 TeV with our previous theoretical proposal that the true Higgs boson HT should be a broad heavy resonance with mass around 750 GeV. We focus on the so-called golden channel HT[Formula: see text]ZZ where the pair of Z bosons decay leptonically to [Formula: see text], [Formula: see text] being either an electron or a muon. We use the data collected by the ATLAS and CMS collaborations at [Formula: see text] = 13 TeV with an integrated luminosity of 36.1 and 77.4 fb[Formula: see text] respectively. We find that the experimental data from both the LHC collaborations do display in the golden channel a rather broad resonance structure around 700 GeV with a sizeable statistical significance. Our theoretical expectations seem to be in fair good agreement with the experimental observations. Combining the data from both the ATLAS and CMS collaborations we obtain an evidence of the heavy Higgs boson in this channel with an estimated statistical significance of more than five standard deviations.
