We present the results from an extensive search for BSM particles in ‘high-mass diphoton events’, a distinctive phase-space indicative of various SM extensions such as Supersymmetry, extra dimensions, and non-minimal Higgs sectors. The searches for both spin-0 and spin-2 particles in resonant as well as non-resonant scenarios were carried out using the full luminosity of the LHC Run-II in proton-proton collisions at \(\sqrt{s} = 13\) TeV with the CMS detector. We place constraints on the production of heavy BSM Higgs bosons and the continuum clockwork mechanism, setting the most stringent limits to date on ADD extra dimensions and RS gravitons, excluding coupling parameters greater than 0.1.

摘要

We present the results from an extensive search for BSM particles in ‘high-mass diphoton events’, a distinctive phase-space indicative of various SM extensions such as Supersymmetry, extra dimensions, and non-minimal Higgs sectors. The searches for both spin-0 and spin-2 particles in resonant as well as non-resonant scenarios were carried out using the full luminosity of the LHC Run-II in proton-proton collisions at \(\sqrt{s} = 13\) TeV with the CMS detector. We place constraints on the production of heavy BSM Higgs bosons and the continuum clockwork mechanism, setting the most stringent limits to date on ADD extra dimensions and RS gravitons, excluding coupling parameters greater than 0.1.
