Perhaps one of the most famous experiments in physics has been giving us the wrong message all these years. For nearly two ...

Figure.1 illustrates the conceptual mechanism of dark-photon production via dark bremsstrahlung and its subsequent decay into invisible dark matter, forming the experimental basis for DarkSHINE, which ...

Researchers, in a recent Physical Review Letters paper, introduce a new mechanism that may finally allow ultralight dark photons to be considered serious candidates for dark matter, with promising ...

The η → e⁺e⁻γ decay channel holds particular significance for dark sector searches, as it provides sensitivity to dark photons and light protophobic X17 bosons that decay into electron-positron pairs.
