Identifying Multi-Top Events from Gluino Decay at the LHC

Understand

We study the LHC signal of a light gluino whose cascade decay is dominated by channels involving top, and, sometimes, bottom quarks.

• This is a generic signature for a number of supersymmetry breaking scenarios considered recently, where the squarks are heavier than gauginos.
• Third generation final states generically dominate since third generation squarks are typically somewhat lighter in these models.
• At the LHC we demonstrate that early discovery is possible due to the existence of multi-lepton multi-bottom final states which have fairly low Standard Model background.
