2 Chiral Quark Dynamics of Baryons Quantum Chromodynamics: with:

Amand Faessler, Tuebingen3 Chiral Quark Dynamics of Baryons 1. P, C, T (exact) 2.Global (and local ) Gauge Invariance: (exact) for each flavor f Effective Lagrangian for low Energies with the same Symmetries as QCD:

Amand Faessler, Tuebingen4 Chiral Quark Dynamics of Baryons From this invariance follows: Conservation of the No quarks of flavor f; -baryon number -electric charge -Third compon. of Isospin -Strangeness -Charm … 3. Approximate Flavor Sym. all the same u, d / SU(2) Isospin; u,d,s / SU(3)

Amand Faessler, Tuebingen5 Chiral Quark Dynamics of Baryons 4. Approximate Chiral Symmetry: Current quark mass at QCD scale  ~ 1 GeV Current mass term: Current quark mass term violates Chiral Symmetry

Amand Faessler, Tuebingen6 Chiral Quark Dynamics of Baryons Low energy effective Lagrangian with correct Symmetries Gluons and Quarks eliminated: -> Chiral Perturbation theory Gluons eliminated but with quarks: -> Perturbative Chiral Quark Model (Manohar and Georgi)

Amand Faessler, Tuebingen7 Chiral Quark Dynamics of Baryons Perturbative Chiral Quark Model A. Manohar and H. Georgi: Nucl. Phys. B234 (1984) 189

Amand Faessler, Tuebingen8 Chiral Quark Dynamics of Baryons Danger of Double Counting in Chiral Quark Model : Pseudoscalar Mesons as Goldstone Bosons and as Quark-Antiquark States Investigated by A. Manohar and H. Georgi: Nucl. Phys. B234 (1984) 189 Goldstone Bosons are the low lying pseudoscalar Mesons. The quark-antiquark states lie very high.

Amand Faessler, Tuebingen9 Chiral Quark Dynamics of Baryons Effective Lagrangian up to fourth order: The quark functions q, the quark momenta, the constituent quark masses, and the chiral fields are of order 1: O(1). Pseudoscalar meson masses, Meson momenta, electroweak potentials are of first order small. Current quark masses, electric and magnetic field tensors F  are of second order small.

Amand Faessler, Tuebingen10 Chiral Quark Dynamics of Baryons With: Do not read this formula! On quark level suggested in leading order by Manohar and Georgi Nucl. Phys. B 234 (1984)189. On hadron level formulated by Gasser, Leutwyler, Holstein, Meissner, Weise, Hemmert, Scherer and others up to fourth order. Leading order Up to fourth order in small quantities.

Amand Faessler, Tuebingen12 Chiral Quark Dynamics of Baryons Parameters and counterterms: c 6,e 7,e 8 fitted to the magnetic moments: Parameters: c 2, c 4,e 10,d 10 fitted to electric and magnetic radii of protons and neutrons: With:

13 Chiral Quark Dynamics of Baryons Formfactor of a single constituent bare quark q = u, d in the Nucleon at high energies can not calculated by chiral perturbation theory. Nucleon expectation value of the bare constituent quark current.

Amand Faessler, Tuebingen14 Can not be calculated by chiral perturbation theory. Bare Constituent Quark Formfactors fixed by High energy Part of the Nucleon Formfactors or by covariant Quark Model Wave Function.

Amand Faessler, Tuebingen15 Chiral Quark Dynamics of Baryons Alternative approach: We use a simple Gaussian Function for the bare quarks (I. V. Anikin et. al. Z. Phys. C65(1995) 681): k 1E and k 2E = Euclidian relative Jacobi momenta  B = 800 MeV k 1E k 2E

Amand Faessler, Tuebingen16 Chiral Quark Dynamics of Baryons We dress now the bare quark current by the pseudoscalar meson cloud of pions, kaons and etas.
