Gluino Axion, Neutrino Seesaw, Dynamical Gaugino Mass, and A = 0 Supersymmetry

TL;DR

This paper proposes a supersymmetric model linking the gluino axion to the neutrino seesaw mechanism, resulting in dynamically generated gaugino masses and a negligible A term, addressing the strong CP problem.

Contribution

It introduces a novel implementation connecting the gluino axion scale with the neutrino seesaw, predicting small A terms and dynamical gaugino mass generation.

Findings

Gaugino masses are generated dynamically.

The A term is predicted to be very small.

The model links the gluino axion scale to neutrino physics.

Abstract

In the axionic solution of the strong CP problem, fermions which transform under quantum chromodynamics (QCD) are required. In supersymmetry, by equating U(1)_{PQ} with U(1)_R, the natural candidates are the gluinos, as pointed out some years ago. A new specific implementation of this idea is proposed, linking the gluino axion scale to that of the canonical seesaw mechanism for neutrinos. Gaugino masses are generated dynamically and the A term is predicted to be very small.
