Direct Bounds on Electroweak Scale Pseudo-Dirac Neutrinos from $\sqrt{s}=8$ TeV LHC Data

Arindam Das, P. S. Bhupal Dev, Nobuchika Okada

Seesaw models with a small lepton number breaking can naturally accommodate electroweak-scale pseudo-Dirac neutrinos with a sizable mixing with the active neutrinos, while satisfyi…
