| Publication Abstract: | The semi-inclusive deep inelastic scattering process, where an electron scatters off a proton target at high enough energy that the process can be described by the scattering off a single constituent particle, offers targeted access to the internal structure of the nucleon. The process can be described in two phases by parton distribution functions (PDFs), which describe the likelihood of finding a quark or gluon in a particular state inside of the nucleon and then by fragmentation functions (FFs) which describe the likelihood of forming a particular final state particle. One way to study these properties is via the measurement of the beam spin asymmetry, loosely defined as the difference in the production cross section of final state particles from partons with opposite intrinsic angular momenta. The internal physical laws that govern this mechanism are dictated in part by the PDFs and FFs that are of interest. Furthermore, when the final state particles include two hadrons these PDFs are more easily accessed and new and exciting FFs emerge. Azimuthal correlations in the production of hadron pairs in semi-inclusive deep-inelastic scattering provide rich information on nucleon structure. A high precision study of data taken with the newly upgraded CLAS12 detector has been used to extract beam-spin asymmetries for the?+? |
