# Accidental dark matter: Case in the scale invariant local B -L model

@article{Guo2015AccidentalDM, title={Accidental dark matter: Case in the scale invariant local B -L model}, author={Jun Guo and Zhaofeng Kang and Pyungwon Ko and Yuta Orikasa}, journal={Physical Review D}, year={2015}, volume={91}, pages={115017} }

We explore the idea of accidental dark matter (aDM) stability in the scale invariant local $U(1)_{B-L}$ model, which is a theory for neutrino and at the same time radiatively breaks scale invariance via quantum mechanical dynamics in the $U(1)_{B-L}$ sector. A real singlet scalar can be accidental DM with an accidental $Z_2$, by virtue of both extended symmetries. A $U(1)_{B-L}$ charged complex scalar can also be a viable accidental DM due to an accidental (or remanent) $Z_3$. They can…
