Weak axial exchange currents for the Bethe-Salpeter equation
We construct weak axial one-boson exchange currents for the BetheSalpeter equation, starting from chiral Lagrangians of the N∆(1236)πρ a1ω system. The currents fulfil the Ward-Takahashi identities and the matrix element of the full current between the two-body solutions of the Bethe-Salpeter equation satisfies the PCAC constraint exactly.
متن کاملRight handed weak currents in sum rules for axial-vector constant renormalization.
The recent experimental results on deep inelastic polarized lepton scattering off proton, deuteron and He together with polarized neutron β-decay data are analyzed. It is shown that the problem of Ellis-Jaffe and Bjorken sum rules deficiency and the neutron paradox could be solved simultaneously by assuming the small right handed current (RHC) admixture in the weak interaction Lagrangian. The p...
متن کاملBaryon axial currents
The baryon axial currents are calculated at one–loop order in heavy baryon chiral perturbation theory by employing both a cutoff and dimensional regularization. Data from the semileptonic baryon decays is used to perform a least–squares fit to the two axial couplings D and F of the effective Lagrangian. Predictions for the momentum dependent axial form factors are made and the two different reg...
متن کاملMeasurement of the Axial Form Factors 13 Axial Singlet Currents &
The proton form factors are reduced to vacuum correlators of 4 quark elds by assuming independent constituent quarks. The axial singlet quark and glu-onic form factors are calculated in the instanton liquid model. A discussion of gauge(in)dependence is given.
متن کاملBaryon Axial Currents in QCD
We prove that the 1/Nc corrections to the baryon axial current matrix elements are proportional to their lowest order values. This implies that the first correction to axial current coupling constant ratios vanishes, and that the SU(2Nf ) spin-flavor symmetry relations are only violated at second order in 1/Nc.
