Antenna subtraction for processes with identified particles at hadron colliders

Blog Article

Abstract Collider processes with identified hadrons in the final state are widely studied in view of determining details of the proton structure and of understanding hadronization.Their theory description requires the introduction of flexcon reverse osmosis water storage tank fragmentation functions, which parametrise the transition of a produced parton into the identified hadron.To compute higher-order perturbative corrections to these processes requires a subtraction method for infrared singular configurations.We extend the antenna subtraction method to read more hadron fragmentation processes in hadronic collisions up to next-to-next-to-leading order (NNLO) in QCD by computing the required fragmentation antenna functions in initial-final kinematics.

The integrated antenna functions retain their dependence on the momentum fractions of the incoming and fragmenting partons.
