Description
I will discuss discovery potential of new physics at hadron colliders using the recently proposed on-shell constrained $M_2$ variables. Particular focus is upon new physics signatures in the top quark sector, for which regular pair-produced top quarks are dominant background. The relevant signal processes are featured by an *asymmetric* event topology, whereas top quark pairs are *symmetric*. I will start with a brief introduction on the on-shell constrained $M_2$ variables, and then design the kinematic variables under the assumption of $t\bar{t}$ event topology, evoking some contradiction in relevant observables. To demonstrate how the technique works, I will take a couple of examples: 1) supersymmetric top partner search and 2) light dark force carrier search.
