Probing the explanation of the muon (g-2) anomaly and thermal light dark matter with the semi-visible dark photon channel
We report the results of a search for a new vector boson ([Formula: see text] ) decaying into two dark matter particles [Formula: see text] of different mass. The heavier [Formula: see text] particle subsequently decays to [Formula: see text] and an off-shell Dark Photon [Formula: see text] . For a...

| description | We report the results of a search for a new vector boson ([Formula: see text] ) decaying into two dark matter particles [Formula: see text] of different mass. The heavier [Formula: see text] particle subsequently decays to [Formula: see text] and an off-shell Dark Photon [Formula: see text] . For a sufficiently large mass splitting, this model can explain in terms of new physics the recently confirmed discrepancy observed in the muon anomalous magnetic moment at Fermilab. Remarkably, it also predicts the observed yield of thermal dark matter relic abundance. A detailed Monte-Carlo simulation was used to determine the signal yield and detection efficiency for this channel in the NA64 setup. The results were obtained re-analyzing the previous NA64 searches for an invisible decay [Formula: see text] and axion-like or pseudo-scalar particles [Formula: see text] . With this method, we exclude a significant portion of the parameter space justifying the muon g-2 anomaly and being compatible with the observed dark matter relic density for [Formula: see text] masses from 2[Formula: see text] up to 390 MeV and mixing parameter [Formula: see text] between [Formula: see text] and [Formula: see text] . |
