Abstract

An exactly solvable large $N$ model is constructed which reduces at low energies to the Standard Model plus the dimension six Higgs-gauge operators $g_{1}^{2} H^{†} H B_{μν} B^{μν}$ , $g_{2}^{2} H^{†} H W_{μν}^{a} W^{a μν}$ , $g_{1} g_{2} H^{†} τ^{a} H W_{μν}^{a} B^{μν}$ , and $ε^{ab c} W_{μ}^{a}^{ν} W_{ν}^{b}^{ρ} W_{ρ}^{c}^{μ}$ . All other dimension six operators are suppressed by powers of $1/ N$ . The Higgs-gauge operators lead to deviations from the Standard Model $h \to γ γ$ and $h \to γ Z$ rates. A simple variant of the model can be used to also generate the Higgs-gluon operator $g_{3}^{2} H^{†} H G_{μν}^{A} G^{A μν}$ which contributes to the Higgs production rate via gluon fusion.
