We consider the multiple point principle (MPP) and the inflation of the gauged B − L (baryon number minus lepton number) extension of the StandardModel (SM) with a classical conformality. We examine whether the scalar couplings and their beta functions can become simultaneously zero at MPP := 1017 GeV by using two-loop renormalization group equations (RGEs).We find that we can actually r…

We consider the multiple point principle of the Standard Model with scalar singlet dark matter (DM) and three heavy right-handed neutrinos at the scale where the beta function βλ of the effective Higgs self-coupling λeff becomes zero.We do a two-loop analysis and find that the top quark mass Mt and theHiggs portal coupling κ are strongly related to each other. One of the go…
