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. Webtwe have calculated the Higgs branching ratios for p, p+∆pand p−∆p, while all other parameters have been left at their central values. The error on each branching ratio has then been determined by ∆p +BR = max{BR(p+∆p),BR(p),BR(p−∆p)}−BR(p) ∆p −BR = BR(p) −min{BR(p+∆p),BR(p),BR(p−∆p)}.
