Sensitivity of the SHiP experiment to dark photons decaying to a pair of charged particles Open
Dark photons are hypothetical massive vector particles that could mix with ordinary photons. The simplest theoretical model is fully characterised by only two parameters: the mass of the dark photon m$_{γ^{\mathrm{D}}}$ and its mixing para…
