Center for Theoretical and Computational Physics
A new Theory Center paper asks the question: What are the low-Q and large-x boundaries of collinear QCD factorization theorems? Using an idealized field-theoretic model that contains the essential elements that a factorization derivation must confront, the paper retraces the steps of factorization approximations and compares with calculations that keep all kinematics exact. It examines the relative importance of the target mass, light quark masses and intrinsic parton transverse momentum, and it finds that a careful accounting of parton virtuality is essential for treating power corrections to collinear factorization for moderately low-Q and large-x physics.
The Installation and Vacuum groups spent an extensive amount of time during the winter scheduled accelerator down period completing many tasks, such as acid flushing all the box power supplies, installing the repaired 750 MHz RF Separator girder and replacing the last of the linac valve position switches with the all-metal upgrades. The group then moved to tasks to support the demonstration runs for the 12 GeV Project Key Performance Parameters in Halls B and C. Additionally, the group completed more infrastructure work in the Upgrade Injector Test Facility.
