dc.abstract.en We present a search for the $e^{+}e^{-}$ decay of a hypothetical dark photon, also named U vector boson, in inclusive dielectron spectra measured by HADES in the p(3.5 GeV) + p, Nb reactions, as well as the Ar (1.756 GeV/u) + KCl reaction. An upper limit on the kinetic mixing parameter squared $\epsilon ^{2}$ at 90% CL has been obtained for the mass range $M_{U}$=0.02-0.55 GeV/$c^{2}$ and is compared with the present world data set. For masses 0.03-0.1 GeV/$c^{2}$, the limit has been lowered with respect to previous results, allowing now to exclude a large part of the parameter region favored by the muon g−2 anomaly. Furthermore, an improved upper limit on the branching ratio of 2.3 $\times 10^{-6}$ has been set on the helicity-suppressed direct decay of the eta meson, $\eta \rightarrow e^{+}e^{-}$, at 90% CL. pl
