The recent Higgs boson data and Higgs triplet model with vectorlike quarks

Abstract

Some vectorlike quarks are added to the Higgs triplet model with the motivation of fitting the recent Higgs boson data released by LHC and Tevatron collaborations. These vectorlike quarks can suppress the cross section of $gg\to h$ sizably, while the charged scalars, especially for the doubly charged scalar, can enhance $Br(h\to \gamma \gamma )$ more sizably. Besides, the Higgs couplings to $WW$, $ZZ$ and light fermions can be the same as their SM values. Thus, the model will enhance the Higgs production rates into $\gamma \gamma$ and $jj\gamma \gamma$, while those for $W{W}^{\ast }$, $Z{Z}^{\ast }$ and $\tau \bar{\tau }$ at the LHC are reduced relative to their SM predictions. The Higgs production rates into $Vb\bar{b}$ at the Tevatron are the same as the SM values.
