Description
Run Group C (RGC) is a series of Electron-nucleon scattering experiments sensitive to target- and double-spin observables. It has been recently performed with the CLAS12 spectrometer in Hall B at Jefferson Lab. The experiments scattered highly polarized 11 GeV electrons by longitudinally polarized proton/neutron targets, a first with the newly upgraded CLAS12. In this presentation, we overview the physics program of the experiment, the experimental setup, and the data collection/processing timeline. We also report on several ongoing analyses: single- and double-spin asymmetries in Deeply Virtual and Timelike Compton Scattering (DVCS and TCS) as well as Semi-Inclusive (SIDIS) and Inclusive (DIS) scattering on the proton and the deuteron/neutron.
