LHC Future Prospects of the 750 GeV Resonance

Abstract

A quantitative discussion on the future prospects of the 750 GeV resonance at the LHC experiment is given using a simple effective field theory analysis. The relative size of two effective operators relevant to diphoton decays can be probed by ratios of diboson signals in a robust way. We obtain the future sensitivities of $Z\gamma$, $ZZ$ and $WW$ resonance searches at the high luminosity LHC, rescaling from the current sensitivities at $\sqrt{s}=13$ TeV. Then, we show that a large fraction of parameter space in the effective field theory will be covered with 300 fb${}^{-1}$ and almost the whole parameter space will be tested with 3000 fb${}^{-1}$. This discussion is independent of production processes, other decay modes and total decay width.
