Ascertaining the origin of the $l\nu l\nu$ excess events at the LHC by a change of beam energy

Abstract

A higher than predicted rate of two leptons plus missing transverse energy events, reported at the summer HEP conferences, can originate from a decay of the Higgs boson into a $W{W}^{(\ast )}$ pair, a misjudgement of the rate of SM background processes or a statistical fluctuation. In this paper we discuss a way to resolve this three-fold ambiguity.
