Precise bounds on the Higgs boson mass
Abstract
We study the renormalization group evolution of the Higgs quartic coupling {lambda}{sub H}. The one loop equation for {lambda}{sub H} is nonlinear and it is of the Riccati type which we analytically and numerically solve in the energy range [m{sub t},E{sub GU}] where m{sub t} is the mass of the top quark and E{sub GU}=10{sup 14} GeV. We find that depending on the value of {lambda}{sub H}(m{sub t}) the solution for {lambda}{sub H}(E) may have a singularity or a zero and become negative in the former energy range so the ultraviolet cutoff of the standard model should be below or equal to the energy where the zero or singularity of {lambda}{sub H} occurs. We then numerically solve the two loop renormalization group equation for {lambda}{sub H} and compare it with the one loop solution. We find that the two loop running of {lambda}{sub H} is very sensitive to the evolution of the top quark Yukawa coupling Y{sub t}. This implies a strong dependence on the top quark mass m{sub t} and suggests that the choice of m{sub t} as the renormalization point, that we use, reduces theoretical errors. We find that in the approximation of one loop for 0.397{<=}{lambda}{sub H}(m{submore »

From the properties of {lambda}{sub H} we then study the predictions for the Higgs mass. We use the effective potential to derive the relation between the Higgs mass and {lambda}{sub H} and obtain that this relation is not very sensitive to the particular choice of the effective potential but for the large Higgs masses the two loop corrections are significant. We determine that the standard model is valid in the whole range [m{sub t},E{sub GU}] for the Higgs masses 153.5{<=}M{sub H}{<=}191.1 for one loop case and 148.5{<=}M{sub H}{<=}193.1 for two loops. The pattern of the behavior of {lambda}{sub H}(E) for different values of {lambda}{sub H}(m{sub t}) indicates the existence of a phase transition in the standard model for {lambda}{sub H}(m{sub t})=0.5 which corresponds to the value of the Higgs mass M{sub H}=m{sub t}.},

We reanalyze our recently proposed mass matrix model based on spontaneously broken discrete chiral family symmetry, taking into account the additional flavor changing neutral current constraint implied by the bound on the D{sub 1}{minus}D{sub 2} mass difference, and including several corrections to our earlier analysis. When combined, the K{sub 1}{minus}K{sub 2} and D{sub 1}{minus}D{sub 2} constraints force the masses of the Higgs particles that contribute most strongly to flavor changing neutral currents (the {phi} Higgs states) to lie above 17 TeV, well beyond the limit of validity of conventional perturbative Higgs physics. The analogous constraints on the masses of themore »

Comment on ''Upper bounds on the HiggsBoson mass and the coupling constant''
It is pointed out that the conditions used by Uchiyama can lead to additional values from the Higgs boson upper mass limit. 
Upper bounds on the HiggsBoson mass and the coupling constant
In the GlashowSalamWeinberg model with single Higgs doublet, upper bounds on the Higgsboson mass and the coupling constant are obtained: m/sub H/< or =455 GeV, lambda< or =32.8 based on oneloop radiative corrections and the existence of the spontaneously broken absolute vacuum. Under twoloop radiative corrections, these bounds are improved to m/sub H/< or =320 GeV, lambda< or =9.35. 
Remarks on the upper bounds on the Higgs boson mass from triviality
We study the effects of the oneloop matching conditions on Higgs boson and top quark masses on the triviality bounds on the Higgs boson mass using {beta}{sub {lambda}} with corrected twoloop coefficients. We obtain quite higher results than previous ones and observe that the triviality bounds are not nearly influenced by varying the top quark mass over the range measured at CDF and D0. The effects of typographical errors in {beta}{sub {lambda}}{sup (2)} and the oneloop matching condition on the top quark mass are negligible. We estimate the size of the effects on the triviality bounds from the oneloop matchingmore »
