Transverse Observables and Mass Determination at Hadron Colliders

Abstract

I consider the two-body decay of a particle at a hadron collider into a visible and an invisible particle, generalizing $W\to e\nu$, where the masses of the decaying particle and the invisible decay particle are, {\em a priori}, unknown. I prove that the transverse mass, when maximized over possible kinematic configurations, can be used to determine both of the unknown masses. I argue that the proof can be generalized to cover cases such as decays of pair-produced superpartners to the lightest, stable superpartner at the Large Hadron Collider.
