A revisit to a compressed supersymmetric spectrum with 125 GeV Higgs

Understand

A compressed spectrum was initially proposed as an explanation for the elusiveness of low-energy supersymmetry (SUSY).

• Some characteristic signals at the Large Hadron Collider (LHC), such as mono-jet + \slashed{E}_T, had been propounded as its trademark signals.
• However, later investigations suggested that lower limits on the supersymmetric particle masses would be quite stringent in spite of compression.
• Also, most compressed SUSY scenarios studied so far are only partially compressed.
