Axial anomaly and transition form factors.
We investigate the properties of the amplitude induced by the anomaly. In a relatively high energy region those amplitudes are constructed by the vector meson poles and the anomaly terms, in which the anomaly terms can be essentially evaluated by the triangle quark graph. We pay our attention to the anomaly term and make intensive analysis of the existing experimental data, i.e., the electromag...
متن کاملDirac Spectrum , Axial Anomaly and the QCD Chiral Phase Transition ∗
The QCD phase transition is studied on 16 and 32 × 4 lattices both with and without quark loops. We introduce a new zero-flavor or quenched species of quark ζ and study the resulting chiral condensate, 〈ζ̄ζ〉 as a function of the ζ mass, mζ . By examining 〈ζ̄ζ〉 for 10 −10 ≤ mζ ≤ 10 we gain considerable information about the spectrum of Dirac eigenvalues. A comparison of ma = 0.01 and 0.025 shows l...
متن کاملEffects of the anomaly on the QCD chiral phase transition
We study a lattice field theory described by two flavors of massless staggered fermions interacting with U(1) gauge fields in the strong coupling limit. We show that the lattice model has a SU(2)× SU(2)×U(1) chiral symmetry and can be used to model the two-flavor QCD chiral phase transition in the absence of the anomaly. It is also possible to add a coupling to this model which breaks the chira...
متن کاملηcγ TRANSITION FORM FACTOR
The ηcγ transition form factor is calculated in a model based on a modified hard scattering approach to exclusive reactions, in which transverse degrees of freedom are taken into account. For the ηc-meson a distribution amplitude of the Bauer-Stech-Wirbel type is used, where the two free parameters, namely the decay constant fηc and the transverse size of the wave function, are related to the F...
متن کاملInduced pseudoscalar form factor of the nucleon at two-loop order in chiral perturbation theory
We calculate the imaginary part of the induced pseudoscalar form factor of the nucleon GP (t) in the framework of two-loop heavy baryon chiral perturbation theory. The effect of the calculated three-pion continuum on the pseudoscalar constant gP = (mμ/2M)GP (t = −0.877mμ) measurable in ordinary muon capture μp → νμn turns out to be negligibly small. Possible contributions from counterterms at t...
