abstract
We consider a fifth force to be an interaction that couples to matter with a strength that grows with the number of atoms. In addition to competing with the strength of gravity a fifth force can give rise to violations of the equivalence principle. Current long range constraints on the strength and range of fifth forces are very impressive. Amongst possible fifth forces are those that couple to lepton flavorful charges $L_e-L_{\mu}$ or $L_e-L_{\tau}$. They have the property that their range and strength are also constrained by neutrino interactions with matter. In this brief note we review the existing constraints on the allowed parameter space in gauged $U(1)_{L_e-L_{\mu}, L_{\tau}}$. We find two regions where neutrino oscillation experiments are at the frontier of probing such a new force. In particular, there is an allowed range of parameter space where neutrino matter interactions relevant for long baseline oscillation experiments depend on the depth of the neutrino beam below the surface of the earth.

Freeze-in at low reheating temperatures allows MeV-scale dark matter in vector portal models to be probed by future direct detection experiments in nuclear recoils for 50-500 MeV masses and via enhanced solar neutrino coherent scattering.
Systematic study of scalar and vector ULDM interactions on long-baseline neutrino oscillations finds order-of-magnitude weaker constraints for m_φ ≲ 10^{-17} eV due to stochastic effects, with combined T2K+NOvA data showing no alleviation of δ_CP discrepancy.
Steep matter-density gradients in neutron stars can produce neutrino-antineutrino pairs analogous to the Schwinger effect.
