  A significant part of the parameter space for light stop squarks still
remains unconstrained by collider searches. For both R-Parity Conserving (RPC)
and R-Parity Violating (RPV) scenarios there are regions in which the stop mass
is around or below the top quark mass that are particularly challenging
experimentally. Here we review the status of light stop searches, both in RPC
and RPV scenarios. We also propose strategies, generally based on exploiting
b-tagging, to cover the unconstrained regions.
