Heavy Higgs Boson

Abstract A search for a heavy Higgs boson H decaying into the observed Higgs boson h with a mass of 125 GeV and another Higgs boson hS is presented. The h and hS bosons are required to decay into a pair of tau leptons and a pair of b quarks, respectively. The search uses a sample of proton-proton collisions collected with the CMS detector at a center-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 137 fb−1. Mass ranges of 240–3000 GeV for mH and 60–2800 GeV for $$ {m}_{{\mathrm{h}}_{\mathrm{S}}} $$ m h S are explored in the search. No signal has been observed. Model independent 95% confidence level upper limits on the product of the production cross section and the branching fractions of the signal process are set with a sensitivity ranging from 125 fb (for mH = 240 GeV) to 2.7 fb (for mH = 1000 GeV). These limits are compared to maximally allowed products of the production cross section and the branching fractions of the signal process in the next-to-minimal supersymmetric extension of the standard model.

Heavy Higgs Boson

We calculate the width (Γ) and differential energy distributions of [Formula: see text] in E6-based models containing one extra U(1). For a fixed Z′ mass, Γ is strongly growing with increasing mH, while for a fixed mH it decreases strongly with increasing mz′. The energy distribution of Z has a pronounced maximum tending to larger energies of Z with increasing mH, for a fixed mz′. In certain parameter ranges, Γ is larger than the width of the [Formula: see text] decay mode.
