Query: Bi-Event Subtraction Technique at Hadron Colliders   We propose the Bi-Event Subtraction Technique (BEST) as a method of modeling
and subtracting large portions of the combinatoric background during
reconstruction of particle decay chains at hadron colliders. The combinatoric
background arises when it is impossible to know experimentally which observed
particles come from the decay chain of interest. The background shape can be
modeled by combining observed particles from different collision events and be
subtracted away, greatly reducing the overall background. This idea has been
demonstrated in various experiments in the past. We generalize it by showing
how to apply BEST multiple times in a row to fully reconstruct a cascade decay.
We show the power of BEST with two simulated examples of its application
towards reconstruction of the top quark and a supersymmetric decay chain at the
Large Hadron Collider.
