Realizing unification in two different SO(10) models with one intermediate breaking scale

Tommy Ohlsson, Marcus Pernow, Erik Sönnerlind

We derive the threshold corrections in $\mathrm{SO}(10)$ grand unified models with the intermediate symmetry being flipped $\mathrm{SU}(5)\times \mathrm{U}(1)$ or $\mathrm{SU}(3)\ti…
