Exploring Elko typical signature

Abstract

We study the prospects of observing the presence of a relatively light Elko particle as a possible dark matter candidate, by pointing out a typical signature for the process encompassing the Elko non-locality, exploring some consequences of the unusual Elko propagator behavior when analyzed outside the Elko axis of propagation. We also consider the production of a light Elko associated to missing energy and isolated leptons at the LHC, with center of mass energy of 7 and 14 TeV and total luminosity from $1f{b}^{-1}$ to $10f{b}^{-1}$. Basically, the Elko non locality engenders a peculiar signal in the missing energy turning it sensible to the angle of detection.
