Detalhes bibliográficos
Resumo:A combination of searches for singly and doubly charged Higgs bosons, \( H^\pm \) and \( H^{\pm\pm} \), produced via vector-boson fusion is performed using \( 140 \text{ fb}^{-1} \) of proton–proton collisions at a centre-of-mass energy of \( 13 \text{ TeV} \), collected with the ATLAS detector during Run 2 of the Large Hadron Collider. Searches targeting decays to massive vector bosons in leptonic final states (electrons or muons) are considered. New constraints are reported on the production cross-section times branching fraction for charged Higgs boson masses between \( 200 \text{ GeV} \) and \( 3000 \text{ GeV} \). The results are interpreted in the context of the Georgi-Machacek model for which the most stringent constraints to date are set for the masses considered in the combination.
