Angular and polarization trails from effective interactions of Majorana neutrinos at the LHeC
Resumen:
We study the possibility of the LHeC facility todisentangle different new physics contributions to the pro-duction of heavy sterile Majorana neutrinos in the leptonnumber violating channel e−p→l+j+3jets (lj≡e,μ). Thisis done investigating the angular and polarization trails ofeffective operators with distinct Dirac–Lorentz structure con-tributing to the Majorana neutrino production, which param-eterize new physics from a higher energy scale. We study anasymmetry in the angular distribution of the final anti-leptonand the initial electron polarization effect on the number ofsignal events produced by the vectorial and scalar effectiveinteractions, finding both analyses could well separate theircontributions
