Abstract:Current searches for the light top squark (stop) mostly focus on the decay channels oft → tχ 0 1 ort → bχ ± 1 → bW χ 0 1 , leading to tt/bbW W + E T final states for stop pair productions at the LHC. However, in supersymmetric scenarios with light neutralinos and charginos other than the neutralino lightest supersymmetric particle (LSP), more than one decay mode of the stop could be dominant. While those new decay modes could significantly weaken the current stop search limits at the LHC, they also offer alter… Show more
