Higher Twist Effects in Parton Fragmentation Functions

Original · EN
We study twist expansions for parton fragmentation functions based on the definition of the twist as an invariant matrix element of a light-cone, bilocal operator. The results are then applied to a method which might be used to extract higher twist effects in the fragmentation sector using both e+ e-, and e- p collisions. We discuss how to apply the later measurements to experiments at the Jefferson National Acceleration Facility.
