Abstract
In this study, Higgs production processes, Higgsstrahlung and vector boson ([Formula: see text] and [Formula: see text]) fusion processes, are investigated for four different future lepton colliders (CEPC, ILC, CLIC, and FCC-ee). The cross-sections for each production process and corresponding backgrounds are calculated considering the Initial State Radiation (ISR) and Beamstrahlung (BS) effects. Various cuts and the b-tagging method are used to reduce the background. Finally, the number of events for each collider is determined, and significance calculations are performed. In our calculations, high event numbers are obtained for all four colliders for the Higgsstrahlung, [Formula: see text], and [Formula: see text] fusion process. This shows that electron–positron colliders will play an important role in future Higgs physics research.
