abstract
A massive, but light abelian U(1) gauge boson is a well motivated possible signature of physics beyond the Standard Model of particle physics. In this paper, the search for the signal of such a U(1) gauge boson in electron-positron pair-production at the spectrometer setup of the A1 Collaboration at the Mainz Microtron (MAMI) is described. Exclusion limits in the mass range of 40 MeV up to 300 MeV with a sensitivity in the mixing parameter of down to $\epsilon^2 = 8\times 10^{-7}$ are presented. A large fraction of the parameter space has been excluded where the discrepancy of the measured anomalous magnetic moment of the muon with theory might be explained by an additional U(1) gauge boson.

Constraining the heavy leptophilic neutral gauge bosons through the $Z\to\ell^+\ell^-$, $W^\pm\to\ell^\pm\nu_\ell$, and $h\to\ell^+\ell^-$ decays
One-loop corrections to W/Z/h leptonic widths exclude heavy leptophilic Z' regions (M ≳ O(1) TeV, g' ≳ 0.4) beyond LEP-2 and neutrino-trident limits.

Constraining Gravitational Dark Matter with LHAASO and Fermi-LAT
Diffuse Galactic gamma-ray data strongly limit the couplings of gravitationally produced decaying dark matter, and the paper claims an oscillation-based bound on massive dark photons.

Testing light and heavy vector mediators with solar CE$\nu$NS measurements
Combined solar CEνNS data from XENONnT, PandaX-4T, and LZ yield competitive constraints on vector NSI and light mediators and a weak mixing angle measurement at low momentum transfer.

A congruous approach with realistic cross section towards limiting sub-GeV dark matter from LUX-ZEPLIN
Using LZ nuclear recoil data, the authors derive 90% CL exclusion limits on cosmic-ray-boosted sub-GeV dark matter for two U(1)' mediator models, with energy-dependent cross sections improving the lower reach versus c...

Simulation of dark photon sensitivity in $\eta \rightarrow \gamma e^+e^-$ at HIAF
Simulations of a proposed HIAF eta factory project a dark photon branching ratio limit of 10^-6 to 10^-7 and a kinetic mixing sensitivity of epsilon^2 about 10^-7 for masses up to 0.4 GeV.
