Web11 de abr. de 2024 · larger Higgs branching ratio to invisible particles for a given BR(h!AA0). • Some models are subject to far stronger constraints because of the oblique parameters or unitarity. • Case I is similar to the fermion mediators and the limits are qualitatively similar. • Case II can potentially avoid contributions to the Web10 de ago. de 2016 · In this paper we ventured to project the 6D parameter space on the 3D space of Higgs masses to obtain the expected range of branching ratios as function of the Higgs mass for each Higgs boson. This allows us to look for the distinctive features between the NMSSM and CMSSM.
