Abstract

The potential for probing extra neutral gauge boson mediators (${Z}^{\ensuremath{'}}$) from low-energy measurements is comprehensively explored. Our study mainly focuses on ${Z}^{\ensuremath{'}}$ mediators present in string-inspired ${E}_{6}$ models and left-right symmetry. We estimate the sensitivities of coherent-elastic neutrino-nucleus scattering ($\mathrm{CE}\ensuremath{\nu}\mathrm{NS}$) and neutrino-electron scattering experiments. Our results indicate that such low-energy high-intensity measurements can provide a valuable probe, complementary to high-energy collider searches and electroweak precision measurements.
