Quarks and Gluon Fragmentation Functions into Photons
L. Bourhis, M. Fontannaz, J. Ph. Guillet
Abstract
The fragmentation functions of quarks and gluons into photons are studied beyond the Leading Logarithm approximation. We address the nature of the initial conditions of the evolution equation solutions and study problems related to factorization scheme invariance. The possibility of measuring these distributions in LEP experiments is discussed, and a comparison with existing data is made.
