Accelerator Readiness Review
Various groups associated with the ARR will have talks, document reviews, in-the-field verifications and demonstrations of lab systems and personnel readiness. The Jefferson Lab ARR effort, lead by ESH&Q, has been preparing documents and assembling subject matter experts to provide answers to the reviewers. The pre-Hot Checkout reviews, conducted by a team of Accelerator Division staff, are key to both identifying readiness issues and preparing for the ARR. The visiting reviewers, all experienced accelerator professionals in their respective fields, will be conducting concurrent sessions for various topics lasting several hours each day.
If you are asked to participate or provide assistance to the ARR effort, it's because your support is needed to demonstrate Jefferson Lab's high level of professional competence to commission and run the accelerator.
Hall C will host the Hall C Summer Workshop Aug. 15-16.
Center for Theoretical and Computational Physics
A new approach has been developed to model the nucleon generalized parton distributions H and E. The approach relies heavily on so-called GPD sum rules that allow one to use functions of just one variable, H(x,x) and E(x,x), instead of the full GPDs H(x,\xi) and E(x,\xi) that depend on two variables, in order to calculate form factors of deeply virtual Compton scattering. The relation between the border functions and usual parton densities measured in deep-inelastic scattering is studied.
