Abstract
Hard exclusive processes have come to the frontier of nucleon structure physics as they offer experimental access to the Generalised Parton Distributions (GPDs). GPDs have quickly risen in importance as they provide a basis for novel representations of the nucleon as an extended object in space (“nucleon tomography”). A lot of excitement about GPDs is connected to the unique possibility for providing access to the total angular momentum carried by quarks and gluons in the nucleon, a question of fundamental importance in QCD spin physics. This contribution aims at giving an overview about existing measurements of hard exclusive processes, which span over a wide kinematic range, as provided by the HERA collider experiments till the JLab fixed target experiments. A brief summary about the status of GPD extractions in global analyses of these data is given as well. More detailed discussions of the various measurements as well as of model calculations and phenomenology of GPDs can be found at http://ecsac.ictp.it/transversity2011/programma.php.
