Exclusive Phi Electroproduction Cross Section Measurement off the Proton at CLAS12

ORAL

Abstract

One of the main research programs motivating the 12 GeV upgrade at Jefferson Lab is the imaging of the 3-dimensional internal structure of the nucleon at high resolution. The exclusive $phi$ electroproduction process off a hydrogen target probes the proton's gluon Generalized Parton Distribution in the valence region, encoding the correlations between transverse position and longitudinal momentum. Additionally, due to its strange content, the phi meson is a unique probe of the gluon content of the proton in the valence region. An update is given on the exclusive $phi$ meson electroproduction cross section measurement at 10.6 GeV by Jefferson Lab's CLAS12 detector.
