Supersymmetry in Slow Motion

TL;DR

This paper introduces new supersymmetric models with discrete symmetries that stabilize the weak scale and predict stable superpartners, potentially observable as R-hadrons and sleptons at the LHC.

Contribution

It presents novel supersymmetric theories combining discrete symmetries to alter decay channels and produce stable superpartners for collider detection.

Findings

Models stabilize the weak scale beyond LHC energies.

Fermion-sfermion-gaugino vertices are absent, changing decay patterns.

Superpartners like R-hadrons and sleptons could be directly observed at the LHC.

Abstract

We construct new theories of electroweak symmetry breaking that employ a combination of supersymmetry and discrete symmetries to stabilize the weak scale up to and beyond the energies probed by the LHC. These models exhibit conventional supersymmetric spectra but the fermion-sfermion-gaugino vertices are absent. This closes many conventional decay channels, thereby allowing several superpartners to be stable on collider time scales. This opens the door to the possibility of directly observing R-hadrons and three flavors of sleptons inside the LHC detectors.
