Residual Local Supersymmetry and the Soft Gravitino.

چکیده
We show that there exists an infinite tower of fermionic symmetries in pure d=4, N=1 supergravity on an asymptotically flat background. The Ward identities associated with these symmetries are equivalent to the soft limit of the gravitino and to the statement of supersymmetry at every angle. Additionally, we show that these charges commute into charges associated with the (unextended) Bondi-Metzner-Sachs (BMS) group, providing a supersymmetrization of the BMS translations.

Electroweak Precision Data and Gravitino Dark Matter
Electroweak precision measurements can provide indirect information about the possible scale of supersymmetry already at the present level of accuracy. We review present day sensitivities of precision data in mSUGRA-type models with the gravitino as the lightest supersymmetric particle (LSP). Theχ fit is based onMW , sin 2 θeff , (g−2)μ, BR(b → sγ) and the lightest MSSM Higgs boson mass, Mh. We...
متن کاملGravitino and Goldstino at Colliders∗
We consider theories with spontaneously broken global or local supersymmetry where the pseudo-goldstino or the gravitino is the lightest superparticle (LSP). Assuming that the long-lived next-to-lightest superparticle (NSP) is a charged slepton, we study several supergravity predictions: the NSP lifetime, angular and energy distributions in 3-body NSP decays. The characteristic couplings of the...
متن کاملNatural soft leptogenesis
Successful soft leptogenesis requires small B-terms for the right-handed sneutrinos and a large CP violating phase between the Aand B-terms. We show that this situation is realized naturally within the framework of gauge mediated supersymmetry breaking. The A-term is dominated by contribution from gauge mediation, while supergravity effects are more important for the B-term. The different origi...
متن کاملPseudo - Goldstino to Gravitino Decay : An Implication of Multiple Supersymmetry Breaking
This thesis studies the decay of a pseudo-goldstino to a gravitino plus a photon in the Minimal Supersymmetric Standard Model. The foundational premise of this decay process is that there are two independent sectors of supersymmetry breaking. We compute this main decay rate using the goldstino equivalence theorem to replace the final gravitino state with a goldstino. This replacement allows us ...
متن کاملSquarks and Sleptons between Branes and Bulk – Gaugino Mediation and Gravitino Dark Matter in an So(10) Orbifold Gut A
We study gaugino-mediated supersymmetry breaking in a six-dimensional SO(10) orbifold GUT model where quarks and leptons are mixtures of brane and bulk fields. The couplings of bulk matter fields to the supersymmetry breaking brane field have to be suppressed in order to avoid large FCNCs. We derive bounds on the soft supersymmetry breaking parameters and calculate the superparticle mass spectr...
