Planck Scale Boundary Conditions and the Higgs Mass

Understand

If the LHC does only find a Higgs boson in the low mass region and no other new physics, then one should reconsider scenarios where the Standard Model with three right-handed neutrinos is valid up to Planck scale.

• We assume in this spirit that the Standard Model couplings are remnants of quantum gravity which implies certain generic boundary conditions for the Higgs quartic coupling at Planck scale.
• This leads to Higgs mass predictions at the electroweak scale via renormalization group equations.
• We find that several physically well motivated conditions yield a range of Higgs masses from 127-142 GeV.
