Understand

We present a method to resolve combinatorial issues in multi-particle final states at hadron colliders.

The use of kinematic variables such as MT2 and invariant mass significantly reduces combinatorial ambiguities in the signal, but at a cost of losing statistics.
We illustrate this idea with gluino pair production leading to 4 jets $+\met$ in the final state as well as $t\bar{t}$ production in the dilepton channel.
Compared to results in recent studies, our method provides greater efficiency with similar purity
