Abstract
Vacuum stability in the Standard Model is problematic as the Higgs quartic self-coupling runs negative at a renormalization scale of about $10^{10}$ GeV. We consider a non-supersymmetric SO(10) grand unification model for which gauge coupling unification is made possible through an intermediate scale gauge group, $G_{\text{int}}=\text{SU}(3)_C\otimes \text{SU}(2)_L\otimes \text{SU}(2)_R \otimes \text{U}(1)_{B-L}$. $G_{\text{int}}$ is broken by the vacuum expectation value of a 126 of SO(10) which not only provides for neutrino masses through the seesaw mechanism but also preserves a discrete $\mathbb{Z}_2$ that can account for the stability of a dark matter cand...

1 We use the three-loop RGEs for the top Yukawa and Higgs quartic couplings. We also include the two-loop electroweak threshold corrections according to Ref. [4]. We use the MS scheme up to the intermediate scale, and switch to the DR scheme at Mint.
