Description

Supersymmetry scenarios in which squarks, particularly in the third generation, are close in mass to the lightest supersymmetric particle are well motivated and offer a possibility for hidden, natural SUSY. Traditional searches are insensitive to these compressed mass spectra scenarios due to the very soft decay products. A search for light top squarks close in mass to the LSP at the CMS detector in 19.7 fb$^{-1}$ of pp collisions at $\sqrt{s}$= 8 TeV is presented using events with one high p$_{T}$ jet and a large transverse energy imbalance. By using monojet events to search for Initial State Radiation produced in association with top squarks, sensitivity to very compressed spectra is attained.
