abstract="A search for a new Z{\textasciiacutex} gauge boson associated with (un)broken B-L symmetry in the keV--GeV mass range is carried out for the first time using the missing-energy technique in the NA64 experiment at the CERN SPS. From the analysis of the data with 3.22{\texttimes}10^11 electrons on target collected during 2016--2021 runs, no signal events were found. This allows us to derive new constraints on the Z{\textasciiacutex}-e coupling strength, which, for the mass range 0.3≲ mZ{\textasciiacutex}≲ 100{\thinspace}{\thinspace}MeV, are more stringent compared to those obtained from the neutrino-electron scattering data.",
