Findings

Establishes a lower bound for the charged-wino to charged-lepton track ratio.

Provides an estimate for the average charged-wino track length.

Applies the theorem to LHC conditions to predict observable signatures.

Abstract

By using kinematical arguments we derive a theorem for the ratio: [production cross-section of charged-neutral wino pairs plus anything else] over [production cross-section of charged-neutral lepton pairs plus anything else]. We do that by working out the consequences of substituting the lepton pair with a wino pair, leaving untouched everything else of the interaction. We apply this result to the possible production of winos at LHC obtaining a lower bound for the ratio of the number of charged-winos over charged-leptons tracks and also find the average charged-wino track length, within a region in the relevant parameter space (e.g. available energy and mass).
