A Generalised Missing Partner Mechanism for SU(5) GUT Inflation
Stefan Antusch, Kevin Hinze, Shaikh Saad +1
We generalise the Missing Partner Mechanism to split the electron-like states from the coloured ones of vectorlike SU(5) 10-plets without fine-tuning. Together with the extra light…
Minimal GUTs with vectorlike fermions
Stefan Antusch, Kevin Hinze, Shaikh Saad
In this work, we attempt to answer the question, "What is the minimal viable renormalizable GUT with representations no higher than adjoints?". We find that an mode…
Singling out SO(10) GUT models using recent PTA results
Stefan Antusch, Kevin Hinze, Shaikh Saad +1
In this work, we construct promising model building routes towards SO(10) GUT inflation and examine their ability to explain the recent PTA results hinting at a stochastic gravitat…
Quark-lepton Yukawa ratios and nucleon decay in SU(5) GUTs with type-III seesaw
Stefan Antusch, Kevin Hinze, Shaikh Saad
We consider an extension of the Georgi-Glashow SU(5) GUT model by a 45-dimensional scalar and a 24-dimensional fermionic representation, where the latter leads to the generation of…
Fully Testable Axion Dark Matter within a Minimal GUT
Stefan Antusch, Ilja Doršner, Kevin Hinze +1
We present a minimal Grand Unified Theory model, based on gauge symmetry and a global Peccei-Quinn symmetry, that predicts the existence of an ultralight axion dark…
