Fitting the Zb b ¯ $$ Zb\overline{b} $$ vertex in the two-Higgs-doublet model and in the three-Higgs-doublet model
Abstract We investigate the new contributions to the parameters g L and g R of the Zb b ¯ $$ Zb\overline{b} $$ vertex in a multi-Higgs-doublet model (MHDM). We emphasize that those contributions generally worsen the fit of those parameters to the experimental data. We propose a solution to this prob...
