From the book
"Quarks, baryons and chiral symmetry" (World Scientific, 2001)

   This book describes baryon models constructed from quarks,
   mesons and chiral symmetry. The role of chiral symmetry and
   of quark model structure with SU(6) spin-flavor symmetry are
   discussed in detail, starting from a pedagogic introduction.
   Emphasis is placed on symmetry aspects of the theories.
   As an application, the chiral bag model is studied for nucleon
   structure, where important methods of theoretical physics,
   mostly related to the semiclassical approach for a system of
   strong interactions, are demonstrated. The text is more
   practical than formal; tools and ideas are explained in detail
   while solving actual problems. By checking each step of
   the computations, readers can learn not only the calculational
   techniques but also the essential ideas behind them.
