| Descripción |
High energy strong interaction physics is successfully described by the local renormalizable
gauge theory called Quantum--Chromo--Dynamics (QCD) with quarks and
gluons as "elementary" degrees of freedom, while intermediate energy strong interaction
physics shows up to be determined by a non--local, non--renormalizable effective
field theory (EFT) of "effective" degrees of freedom like mesons, ground state
baryons and resonances. The connection between high and intermediate physics is
established by a change of basis ("bosonisation") from the infinite Fock--state basis
of quarks and gluons to the infinite Fock--state basis of the "effective" degrees
of freedom. The infinite number of counter terms in the Lagrangian of such an
non--renormalizable EFT is replaced by a tree--level Lagrangian containing a finite
number of interaction terms dressed by non--local vertex--functions commonly called
formfactors (containing cutoffs) generating the dynamics of an infinity of interaction
diagrams i...
