A narrow scalar resonance at 325 GeV?
Krzysztof A. Meissner, Hermann Nicolai
TL;DR
This paper suggests that an observed excess of four-lepton events at 325 GeV could be due to a new narrow scalar particle, similar to the Standard Model Higgs, predicted by the Conformal Standard Model.
Contribution
It introduces the hypothesis of a sterile scalar resonance at 325 GeV explaining the event excess, linking it to the Conformal Standard Model framework.
Findings
Possible identification of a new scalar resonance at 325 GeV
The resonance has a narrow width and similar branching ratios to the Higgs
Supports the existence of a sterile scalar particle in the Conformal Standard Model
Abstract
We propose to identify the excess of events with four charged leptons at seen by the CDF and CMS Collaborations with a new `sterile' scalar particle characterized by a very narrow resonance of the same height and branching ratios as the Standard Model Higgs boson, as predicted in the framework of the so-called Conformal Standard Model
