Dileptonic scalar dark matter and exotic leptons

A simple scenario of long-lived dark matter is presented. Assuming lepton number (L) conservation with Dirac neutrinos, the neutral component of an SU(2)L scalar triplet with L=2 is a suitable candidate, which decays to two neutrinos. Exotic leptons with L=−1 may also play a role, and act as anchors...
