Probing light dark matter with positron beams at NA64

We present the results of a missing-energy search for light dark matter which has a new interaction with ordinary matter transmitted by a vector boson, called dark photon A ′ . For the first time, this search is performed with a positron beam by using the significantly enhanced production of A ′ in...
