Axion dark matter, proton decay and unification
Journal of High Energy Physics, 2020 We discuss the possibility to predict the QCD axion mass in the context of grand unified theories. We investigate the implementation of the DFSZ mechanism in the context of renormalizable SU(5) theories.

Liberating methodological thinking in human sciences from grand theories
Akademisk Kvarter, 2016 Many humanistic and social disciplines are naturally inclined to seek for human-, person-, self- centered focus, and develop a holistic theory of such. Such disciplines continually engage with philosophical, metaphysical and meta-theoretical perspectives.

Grand unified theories in renormalisable, classically scale invariant gravity
Journal of High Energy Physics, 2019 We analyze SO(N) and SU(N) gauge theories with scalars in adjoint and fundamental representations, coupled to renormalisable, classically scale invariant gravity.

Origins of inert Higgs doublets
Nuclear Physics B, 2016 We consider beyond the standard model embedding of inert Higgs doublet fields. We argue that inert Higgs doublets can arise naturally in grand unified theories where the necessary associated Z2 symmetry can occur automatically.

Threshold corrections to dimension-six proton decay operators in non-minimal SUSY SU(5) GUTs
Nuclear Physics B, 2016 We calculate the high and low scale threshold corrections to the D=6 proton decay mode in supersymmetric SU(5) grand unified theories with higher-dimensional representation Higgs multiplets. In particular, we focus on a missing-partner model in which the

A clockwork solution to the doublet-triplet splitting problem
Physics Letters B, 2021 Maybe the biggest puzzle in grand unified theories (GUTs) is the apparent large splitting of the doublet and triplet Higgs masses. We suggest a novel mechanism to solve this puzzle, which relies on the clockwork mechanism to generate large hierarchies ...

Scaling solution for field-dependent gauge couplings in quantum gravity
Nuclear Physics B, 2022 Quantum gravity can determine the dependence of gauge couplings in a scalar field, which is related to possible fifth forces and time varying fundamental “constants”. This prediction is based on the scaling solution of functional flow equations.

Dark matter from the vector of SO(10)
Physics Letters B, 2016 SO(10) grand unified theories can ensure the stability of new particles in terms of the gauge group structure itself, and in this respect are well suited to accommodate dark matter (DM) candidates in the form of new stable massive particles. We introduce

FINITE GRAND UNIFIED THEORIES AND INFLATION [PDF]
International Journal of Modern Physics A, 1998 A class of finite GUT's in curved space–time is considered in connection with the cosmological inflation scenario. It is confirmed that the use of the running scalar-gravitational coupling constant in these models helps realizing a successful chaotic inflation. The analyses are made for some different sets of the models.

Accidental SO(10) axion from gauged flavour
Journal of High Energy Physics, 2020 An accidental U(1) Peccei-Quinn (PQ) symmetry automatically arises in a class of SO(10) unified theories upon gauging the SU(3) f flavour group. The PQ symmetry is protected by the ℤ4 × ℤ3 center of SO(10) × SU(3) f up to effective operators of canonical
