Viable Alternative to the Standard Model

Abstract

As an alternative to the standard model, we couple two scalar doublets such that, in the third family, one ($\mathcal{H}$) couples only to the top quark, the other ($H$), that is identified as the 126 GeV state already observed, to the bottom quark and the tau lepton. Three explicit predictions of the model are that the partial decay rate $\Gamma (H\to \gamma \gamma )$ is 28.1\% higher than predicted by the standard model, and the two partial decay widths $\Gamma (H\to \bar{b}b)$ and $\Gamma (H\to \bar{\tau }\tau )$ are both predicted to be greater than, or equal to, their standard model values.
