520.3.#.a: We obtain the mass spectrum and the Higgs self-couplings of the two Higgs doublet model (THDM) in an alternative unification scenario where the parameters of the Higgs potential λi (i = 1, 2, 3, 4, 5) are determined by imposing their unification on the electroweak gauge couplings. An attractive feature of this scenario is the possibility of determining the Higgs boson masses by evolving the λi from theelectroweak-Higgs unification scale MGH down to the electroweak scale. The unification condition for the gauge (g1, g2) and Higgs cou- plings is written as g1 = g2 = f(λi), where g1 = k1/2 Y gY , and kY isthe normalization constant. Two variants for the unification condition are discussed: Scenario I is defined through the linear relation: g1 = g2 = kH(i)λi(MGH), while Scenario II assumes a quadratic relation g 2 1 = g 2 2 = kH(i)λi(MGH). In Scenario I, by setting ad hoc −kH(5) = 1 2 kH(4) = 3 2 kH(3) = kH(2) = kH(1) = 1, taking tan β = 1 and using the standard normalization (kY = 5/3), we obtain the following spectrum for the Higgs boson masses: mh0 = 109.1 GeV, mH0 = 123.2 GeV, mA0 = 115.5 GeV, and mH± = 80.3 GeV, with similar results for other normalizations such as kY = 3/2 and kY = 7/4.

Resumen
We obtain the mass spectrum and the Higgs self-couplings of the two Higgs doublet model (THDM) in an alternative unification scenario where the parameters of the Higgs potential λi (i = 1, 2, 3, 4, 5) are determined by imposing their unification on the electroweak gauge couplings. An attractive feature of this scenario is the possibility of determining the Higgs boson masses by evolving the λi from theelectroweak-Higgs unification scale MGH down to the electroweak scale. The unification condition for the gauge (g1, g2) and Higgs cou- plings is written as g1 = g2 = f(λi), where g1 = k1/2 Y gY , and kY isthe normalization constant. Two variants for the unification condition are discussed: Scenario I is defined through the linear relation: g1 = g2 = kH(i)λi(MGH), while Scenario II assumes a quadratic relation g 2 1 = g 2 2 = kH(i)λi(MGH). In Scenario I, by setting ad hoc −kH(5) = 1 2 kH(4) = 3 2 kH(3) = kH(2) = kH(1) = 1, taking tan β = 1 and using the standard normalization (kY = 5/3), we obtain the following spectrum for the Higgs boson masses: mh0 = 109.1 GeV, mH0 = 123.2 GeV, mA0 = 115.5 GeV, and mH± = 80.3 GeV, with similar results for other normalizations such as kY = 3/2 and kY = 7/4.
