Vacuum stability Higgs boson mass bound reexamined with implications for extra dimension theories

We take the standard model to be an effective theory including higher dimensional operators suppressed by a scale Λ and reexamine the Higgs boson mass bounds from the requirements of vacuum stability. Our results show that the effects of the higher dimensional operators on the Higgs boson mass limits are significant. As an implication of our results, we study the vacuum stability Higgs boson mass bounds in theories with extra dimensions.
