We derive the energy and angle correlation of the dilepton final state, both for like-sign ($e^{\\mp}e^{\\mp}$) and unlike-sign ($e^-e^+$) configurations. Interesting differences are found between the cases $\\eta_{CP}=+1$ and $-1$. The characteristics of unlike-sign $e^+e^-$ dileptons originating from a Majorana pair $N_1N_2$ are contrasted with those arising from the reaction $e^+e^-\\to N\\bar{N}\\to W^+e^-W^-e^+$, where $N\\bar{N}$ is a Dirac particle-antiparticle pair.", "revisions": [ { "version": "v1", "updated": "1996-03-06T18:41:27.000Z" } ], "analyses": { "subjects": [ "14.60.St", "11.30.Er", "13.35.Hb" ], "keywords": [ "heavy majorana neutrinos", "pair production", "correlated decay", "collisions", "dirac particle-antiparticle pair" ], "tags": [ "journal article" ], "publication": { "publisher": "APS", "journal": "Phys.
