    1816The GM model can thus be a useful benchmark for the study of Higgs properties as well as searches for additional scalars.

    20 The doublet vev   v_phi  and the triplet vevs v_chi are constrained by
    21 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.
     18The doublet vev   [[latex($v_\phi$)]]  and the triplet vevs [[latex(v_\chi)]] are constrained by
     19[[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.

    2321The 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.
