N2 - We present lower bounds on the Higgs boson mass in the Standard Model with three and four fermion generations, SM(S14), as well as upper bounds on the lightest Higgs boson mass in the minimal supersymmetric extension of the SM with three and four generations, MSSM(3, 4). Our analysis utilizes the SM(3, 4) renormalization-group-improved one-loop effective potential of the Higgs boson to find the upper bounds on the Higgs mass in the MSSM(3, 4), while the lower bounds in the SM(3, 4) are derived from considerations of vacuum stability. All the bounds increase as the degenerate fourth generation mass increases, providing more room in theory space that respects the increasing experimental lower limit of the Higgs mass.
