Probing the seesaw mechanism at the 250 GeV ILC

We consider a gauged U(1)B−L (Baryon-minus-Lepton number) extension of the Standard Model (SM), which is anomaly-free in the presence of three Right-Handed Neutrinos (RHNs). Associated with the U(1)B−L symmetry breaking the RHNs acquire their Majorana masses and then play the crucial role to generat...
