Dark-Sector Search via Pion-Produced η and η′ Mesons Decaying Invisibly in the NA64h Detector / NA64 Collaboration
We present the first results from a proof-of-concept search for dark sectors via invisible decays of pseudoscalar η and η′ mesons in the NA64h experiment at the CERN SPS. Our novel technique uses the charge-exchange reaction of 50 GeV π- on nuclei of an active target as the source of neutral mesons. [...]
