Searching for supersymmetry in compressed scenarios with the CMS experiment

Searches for supersymmetric models with a compressed mass spectrum are presented using data samples collected at a centre-of-mass energy of 8 TeV with the CMS detector at the LHC and corresponding to an integrated luminosity of 19.4$-$19.7~$fb^{-1}$. This class of model is challenging to detect experimentally, primarily due to low-momentum SM particles arising from decay chains involving SUSY particles of comparable mass. Various searches that are optimised for models involving the production of coloured sparticles or electroweakinos and a compressed mass spectrum are presented.
