Dirac, Majorana, and Weyl Spinors in Arbitrary Dimension and Signature
Jan Hajer
Fermionic field types in arbitrary signature are often inferred from complex Spin representations alone, which obscures distinctions associated with real structures, disconnected s…

Neutrino oscillation data and a pseudo-Dirac heavy neutral lepton
Jan Hajer
Symmetry-protected seesaw models can accommodate light-neutrino oscillation data while keeping heavy neutral leptons (HNLs) within collider reach. In these models, the smallness of…
