Zusammenfassung:Doubly charged scalars are common figures in several beyond the Standard Model studies, especially those related to neutrino masses. In this work, we estimate the High-Luminosity (HL-LHC) and High-Energy LHC (HE-LHC) sensitivity to doubly charged scalars assuming they decay promptly and exclusively into charged leptons. Our study focuses on the fit to the same-sign dilepton mass spectra and it is based on proton-proton collisions at \(13\) TeV, \(14\) TeV and \(27\) TeV with integrated luminosity of \(\mathcal{L}=139 fb^{-1}, 3 \)ab\(^{-1}\) and \(15\)ab\(^{-1}\). We find that HL-LHC may probe doubly charged scalars masses up to \(2.3\) TeV, whereas HE-LHC can impressively probe masses up to \(3\) TeV, conclusively constituting a complementary and important probe to signs of doubly charged scalars in lepton flavor violation decays and lepton-lepton colliders.
