@article{Iwamoto2021OneloopCT, title={One-loop corrections to light neutrino masses in gauged U(1) extensions of the standard model}, author={Sho Iwamoto and Timo J. K{\"a}rkk{\"a}inen and Zolt'an P'eli and Zolt'an Tr'ocs'anyi}, journal={Physical Review D}, year={2021} }

We consider gauged U(1) extensions of the standard model of particle physics with three right-handed sterile neutrinos and a singlet scalar. The neutrinos obtain mass via the type I seesaw mechanism. We compute the one loop corrections to the elements of the tree level mass matrix of the light neutrinos and show explicitly the cancellation of the gauge dependent terms. We present a general formula for the gauge independent, finite one-loop corrections for arbitrary number new U(1) groups, new…
