Abstract
The phenomenology of supersymmetric theories with low scale supersymmetry breaking and a squark as the lightest standard model superpartner are investigated. Such squarks hadronize with light quarks, forming sbaryons and mesinos before decaying. Production of these supersymmetric bound states at a high energy collider can lead to displaced jets with large negative impact parameters. Neutral mesino-antimesino oscillations are not forbidden by any symmetry and can occur at observable rates. Stop mesino-antimesino oscillations would give a sensitive probe of up-type sflavor violation, and can provide a discovery channel for supersymmetry through events with a same-sign top-top topology.
