Indiana-Illinois Workshop on Fragmentation Functions

Welcome to the Indiana-Illinois Workshop on Fragmentation Functions!

Overview

Bloomingon, IN
December 12-14, 2013

Fragmentation is the QCD process for which partons hadronize to colorless hadrons. Being a non-perturbative process, it is not possible to describe it ab initio, and it is parametrized with fragmentation functions. Fragmentation functions are not only interesting as they shed light on parton hadronization and confinment, but are also needed for a complete description of the internal structure of the proton, QCD fundamental state.

This workshop aims to provide a forum for theorists and experimentalists to discuss the new results with the goal to improve our understanding of the fragmentation process and the QCD effects governing it, as well as to evaluate the impact the improved knowledge on fragmentation functions will have on probing nucleon structure in semi inclusive processes.

The scientific program of the workshop intend to cover the progress in the knowledge of unpolarized as well as polarized fragmentation functions. In addition, with new experimental programs on the horizon at Jefferson Laboratory and KEK and the the growing understanding of soft-scale QCD effects in the theoretical community, we hope to contribute to the identification of key measurements and calculations necessary to advance this growing field.
