Motivated by an anomaly observed in the decay of an excited state of Beryllium by the Atomki collaboration, we study an extension of the Standard Model with a gauged $U(1)'$ symmetry in presence of a 2-Higgs Doublet Model structure of the Higgs sector. We show that this scenario complies with a variety of experimental results and is able to explain the potential presence of a resonant spin-1 gauge boson, $Z'$, with a mass of 17 MeV in the Atomki experimental data, for appropriate choices of $U(1)'$ charges and Yukawa interactions.

    A chiral flavor-specific U(1)_X model with two Higgs doublets accommodates the ATOMKI 17 MeV anomaly via a Z' boson whose parameter space remains consistent with atomic parity violation, beam dump, meson decay, and ne...

    Fitting independent quark couplings of the X17 boson to D, psi(2S), and phi decay data yields |ε_c| = 7.6×10^{-3}, |ε_s| = 2.4×10^{-3}, a huge |ε_u| in tension with ATOMKI, and a predicted range for the D^{*+} → D^{+}...
