Sudakov Resummation in Small-x Saturation Formalism

Understand

Through an explicit calculation of massive scalar particle (e.g., Higgs boson) production in high energy pA collisions up to one-loop order, we demonstrate that the Sudakov-type logarithms in hard processes in small-x saturation formalism can be systematically separated from the typical small-x logarithms.

• The generic feature of the Sudakov logarithms and all order resummation is derived.
• We further comment on the phenomenological implications and extension to other hard processes in the small-x calculations.
