neutrino masses observed in neutrino oscillation experiments. When the sterile neutrinos …

Distinguishing seesaw models at LHC with multi-lepton signals

F Del Aguila, JA Aguilar-Saavedra - Nuclear Physics B, 2009 - Elsevier
We investigate the LHC discovery potential for electroweak scale heavy neutrino singlets

Effects of new leptons in electroweak precision data

F Del Aguila, J De Blas, M Perez-Victoria - Physical Review D—Particles, Fields …, 2008 - APS
