Abstract

Within one loop approximation, the renormalization group analysis of the Higgs boson mass is performed with an initial condition induced by mH=2mWm_{_H}=\sqrt{2}m_{_W} which is presented in the new scheme of our noncommutative differential geometry for the reconstruction of the standard model. This initial condition holds at energy derived from g2=(5/3)g2g^2=(5/3)g'^2 with the running SU(2)L_{_L} and U(1)Y_{_Y} gauge coupling constants. sin2θW=3/8\sin^2\theta_{_W}=3/8 is obtained under same conditions. However, contrary to SU(5){\rm SU(5)} GUT without supersymmetry, the grand unification of coupling constant is not realized in this scheme. The physical mass of the Higgs boson considerably depends on the top quark mass mtopm_{top} since the top quark Yukawa coupling constants gives a large negative contribution to β\beta function of the Higgs quartic coupling constant in wide range. The Higgs boson mass varies from 153.42GeV to 191.94GeV corresponding to 168GeVmtop192GeV168{\rm GeV}\leq m_{top}\leq 192{\rm GeV}. We find mH=164.01m_{_H}=164.01GeV for mtop=175 m_{top}=175GeV and mH=171.92m_{_H}=171.92GeV for mtop=180 m_{top}=180GeV.
