Constraints on fourth generation Majorana neutrinos.

Lenz, Alexander and Pas, Heinrich and Schalla, Dario (2010) 'Constraints on fourth generation Majorana neutrinos.', Journal of physics : conference series., 259 (1). 012096.


We investigate the possibility of a fourth sequential generation in the lepton sector. Assuming neutrinos to be Majorana particles and starting from a recent - albeit weak - evidence for a non-zero admixture of a fourth generation neutrino from fits to weak lepton and meson decays we discuss constraints from neutrinoless double beta decay, radiative lepton decay and like-sign di-lepton production at hadron colliders.
