| Abstract |
We study a Dirac neutrino mass model of Davidson and Logan. In the model, the smallness of the neutrino mass is originated from the small vacuum expectation value of the second Higgs of two Higgs doublets. We study the one-loop effective potential of the Higgs sector and examine how the small vacuum expectation is stable under the radiative correction. By deriving formulas of the radiative correction, we numerically study how large the one-loop correction is and show how it depends on the quadratic mass terms and quartic couplings of the Higgs potential. The correction changes depending on the various scenarios for extra Higgs mass spectrum.
