where N is the number of selected events, N BG is the number of background events, f ξ < 5 × 10-6 is the fraction of events that pass the event selection but have ξ<5×10 −6, is the integrated ...
Photonuclear reactions occur when high-energy photons interact with atomic nuclei, resulting in the ejection of one or more nucleons or the emission of other subatomic particles. These reactions serve ...
