Our construction proceeds by first constructing the superparticle in a flat background. Next, by boosting up the background symmetries, we replace in a first step the flat background by a Galilean supergravity background. In a second step the Galilean supergravity background is replaced by a Newton-Cartan supergravity background. We extend our results by adding a supersymmetric cosmological constant and compare the nonrelativistic superparticle with the relativistic κ -symmetric three-dimensional superparticle.16 p.application/pdfeng(c) American Physical Society, 2014Física de partículesSupergravetatSupersimetriaParticle physicsSupergravitySupersymmetryinfo:eu-repo/semantics/article6443852019-04-05info:eu-repo/semantics/openAccess
