We describe an explicit N=2 supergravity model where an arbitrarily light vector boson ("graviphoton") is coupled, with typical gravitational strength to matter hypermultiplets, possessing unbroken gauge interactions as well. We discuss: i) the mass and the couplings of the graviphoton; ii) the consistency of its coupling to a mass generated by the Higgs mechanism; iii) the actual composition of the graviphoton in terms of the original vector fields of the Lagrangian (e.g. its mixing with the photon).

Abstract

We describe an explicit N=2 supergravity model where an arbitrarily light vector boson ("graviphoton") is coupled, with typical gravitational strength to matter hypermultiplets, possessing unbroken gauge interactions as well. We discuss: i) the mass and the couplings of the graviphoton; ii) the consistency of its coupling to a mass generated by the Higgs mechanism; iii) the actual composition of the graviphoton in terms of the original vector fields of the Lagrangian (e.g. its mixing with the photon).
