Improved limits on a new $Z^{'}$ in $B - L$ scenarios with the NA64 experiment at CERN

The NA64 Collaboration, Yu. M. Andreev, A. Antonov +53

Extensions of the Standard Model featuring an additional $U (1)_{B - L}$ gauge symmetry provide a compelling framework linking the origin of neutrino masses to possible dark matter ca…
