Mixing stops at the LHC

Understand

We study the phenomenology of a light stop NLSP in the presence of large mixing with either the first or the second generation.

• R-symmetric models provide a prime setting for this scenario, but our discussion also applies to the MSSM when a significant amount of mixing can be accommodated.
• In our framework the dominant stop decay is through the flavor violating mode into a light jet and the LSP in an extended region of parameter space.
• There are currently no limits from ATLAS and CMS in this region.
