QCD microsurgery of hadrons at HERA via hard quasielastic processes.
--------------------------------------------------------------------
 
Abstract:
========= 
The QCD factorization theorem for hard exclusive processes is considered.
In the ``microsurgery" of a nucleon, a variety of skewed parton
distributions are highlighted. Characteristics of basic features of hard
exclusive processes at small and moderately small x are considered.  
Measurements of the electroproduction of pseudoscalar mesons and the
extraction of the valence quark distribution of the spin of a nucleon are
discussed as a probe of spontaneously broken chiral symmetry. Further
topics will include the Colour Transparency phenomenon and new ideas of
searching for glueballs, and of implanting strangeness into nuclei.
