Description
DarkSHINE is a proposed fixed-target experiment at SHINE aimed at searching for sub-GeV dark-sector mediators and light dark matter.
Its baseline target is an invisibly decaying dark photon (A′→χχˉ) produced in high-intensity electron–nucleus interactions, observed through a missing-energy/momentum signature.
We present the experimental concept, baseline detector design, and a first prospective sensitivity study.
We also report recent R&D progress and discuss future extensions, including a positron-beam mode. DarkSHINE will be complementary to NA64 and LDMX experiments.
