Soft-collinear effects for prompt photon production via fragmentation    [PDF]

Rahul Basu, Eric Laenen, Anuradha Misra, Patrick Motylinski

We study the impact of leading soft-collinear effects on threshold and joint-resummed calculations for the production of prompt photons via parton fragmentation, complementing a previous study for direct production. We assess these effects for both fixed-target and collider kinematics. We find them to be small, but noticeable and comparable to the direct case.
