Description
We discuss the prospects of searches for pair production
 at the LHC with forward  proton detectors
of new BSM states with subsequent decays into cosmologically
stable dark matter.
As a topical example we consider production of slepton and chargino pairs
in the MSSM with compressed mass spectra, where the natural candidate for cold dark matter is 
the  lightest neutralino.
Special attention is paid to various challenges which such searches face
in the case of high pile-up environment.
