Compressed spectra remains a natural hideout for many beyond standard model scenarios. The lack of visible energy in the final state results in a much weaker bound on the new physics (NP) particles. The final state topology is simple, consisting of a single hard jet and missing energy. However, the information at hand is minimalistic in nature. Therefore, it is hard to increase the signal purity and sensitivity with the traditional observables. In this light, the inclusion of soft tracks, which carries the information of particle multiplicities in an event can increase the signal sensitivity by many orders. We will present our results in a toy model to start with and then apply this idea in two beyond standard model scenarios, such as, compressed MSSM and MUED. Our results show that compressed MUED can already be ruled out with the present data.
