Abstract:Understanding various fundamental properties of nucleons and nuclei are among the most important scientific goals at the upcoming Electron-Ion Collider (EIC). With the unprecedented opportunity provided by the next-generation machine, the EIC might provide definitive answers to many standing puzzles and open questions in modern nuclear physics. Here we investigate one of the golden measurements proposed at the EIC, which is to obtain the spatial gluon density distribution within a lead (P b) nucleus. The propo… Show more
“…Incoherent events can be isolated by identifying the break-up of the excited nucleus. The evaporated neutrons produced by the break-up in the diffraction process can be used in most cases (about 90%) to separate coherent processes [19]. In addition, photons from the de-excitation of the excited nuclei can help identify incoherent processes even in the absence of evaporated neutrons.…”
