Journal ArticleDOI
Radiative corrections to the supersymmetric neutral Higgs boson masses
TL;DR: In this article, the radiative corrections to the masses of the neutral Higgs bosons in the minimal supersymmetric standard model were computed by finding the propagator poles, instead of approximating them with the second derivatives of the affective potential.
Journal ArticleDOI
On the effective interactions of a light gravitino with matter fermions
TL;DR: In this article, the authors derived the four-point effective coupling involving two matter fermions and two goldstinos, by explicit integration of the heavy spin-0 degrees of freedom in the low-energy limit.
Journal ArticleDOI
Signals of a superlight gravitino at hadron colliders when the other superparticles are heavy
TL;DR: In this paper, the cross-section for the process e + e → ǫ G ˜ G, whose final state can give rise to a distinctive photon plus missing energy signal at present and future e+ e colliders, is computed.
Journal ArticleDOI
Aspects of spontaneously broken N=1 global supersymmetry in the presence of gauge interactions
TL;DR: In this paper, the authors discuss models where N = 1 global supersymmetry is spontaneously broken, at the classical level, in the presence of non-anomalous gauge interactions, with special attention to the behaviour of some four-particle scattering amplitudes in the high and low energy limits.
Journal ArticleDOI
Signals of a superlight gravitino at e^+ e^- colliders when the other superparticles are heavy
TL;DR: In this article, the cross-section for the process e+ e+ ==> G G gamma, whose final state can give rise to a distinctive photon plus missing energy signal at present and future e^+ e^- colliders, is computed.
