Least supersymmetric standard model

Authors: Antonio Delgado; Mariano Quirós;

Least supersymmetric standard model

Abstract

We propose the minimal (least) version of the supersymmetric standard model which can solve the hierarchy problem in the same way as the so-called minimal supersymmetric standard model and presents solutions to some of its problems. Supersymmetry is broken in a secluded sector and mediated to the observable sector by messengers of a gauge group $G$ under which the first two generations transform. The group $G$ spontaneously breaks (almost) supersymmetrically at a scale at most a few orders of magnitude below the scale of gauge messengers ${M}_{*}\ensuremath{\sim}{10}^{15}\text{ }\text{ }\mathrm{GeV}$. By gauge mediation, sfermions of the first two generations acquire supersymmetry breaking masses $\stackrel{^}{m}\ensuremath{\sim}10\text{ }\text{ }\mathrm{TeV}$. Supersymmetry breaking is also mediated by gravity which generates masses for all sfermions, Higgsinos, and gauginos at the TeV scale and can provide appropriate values to the $\ensuremath{\mu}$ and ${B}_{\ensuremath{\mu}}$ parameters by $D$-term effective operators. If gravity mediation is minimal flavor violating there is no supersymmetric flavor problem. In the presence of $R$-parity dark matter can be the lightest neutralino, as in the minimal supersymmetric standard model, and the LHC model phenomenology is characterized by the fact that only third-generation squarks and sleptons are present.
