 v39 The doublet vev   [[latex($v_\phi$)]]  and the triplet vevs [[latex(v_\chi)]] are constrained by [[latex(v_\phi^2 + 8 v_\chi^2 = v_{SM}^2)]]  to ensure the model generates the measured W and Z boson masses. We parametrize the relative size of the vevs by tan \theta_H = 2 \sqrt(2) v_chi/v_phi. [[latex($v_\phi^2 + 8 v_\chi^2 = v_{SM}^2$)]]  to ensure the model generates the measured W and Z boson masses. We parametrize the relative size of the vevs by [[latex($\tan \theta_H = 2 \sqrt{2} v_\chi/v_\phi$)]]. The scalars (apart form Goldstone bosons) in this model can be classified as two custodial SU(2) singlets, a triplet and a fiveplet. The two custodial singlets mix by an angle alpha to give eigenstates h and H, one of which is the 125 GeV Higgs.
