Axial Anomaly Effects in Pion and Z0 Radiative Decays
نویسندگان
چکیده
We discuss a connection between axial anomaly and polarized radiative processes. By comparison with the corresponding unpolarized cases, we consider some physical outputs for the π+ and Z0 polarized radiative decays. We analyse in detail the pattern of mass singularity cancellation. PACS 11.30.Rd, 13.20.Cz, 11.15.Bt

Axial Anomaly and Polarized Radiative Decays
We extend the approach of Dolgov and Zakharov to the axial anomaly to study polarized radiative decays. We analyse the pattern of mass singularity cancellation in the corresponding decay rates. We compare polarized and unpolarized cases. The cancellation of the infrared and collinear singularities is verified to all powers of the lepton mass for the π+ and Z0 polarized radiative decays.

متن کاملAxial-vector currents and τ mesonic decays
A general expression of the axial-vector current is presented, in which both the effects of the chiral symmetry breaking and the spontaneous chiral symmetry breaking are included. A new resonance formula of the axial-vector meson is derived and in the limit of q → 0 this formula doesn’t go back to the “chiral limit“. The studies show that the dominance of the axial-vector meson is associated wi...
متن کاملmesonic decays and strong anomaly of PCAC
It is shown that the matrix elements of the quark axial-vector currents of the decays τ → ωππν and ωρν are not conserved in the limit of mq = 0. Pion exchange dominates the decay mode τ → ωρν. Theoretical result of τ → ω(ππ)nonρν agrees with data well. Both the decay modes provide evidences for the existence of strong anomaly of the PCAC. The strong anomaly originates in the Wess-Zumino-Witten ...
متن کاملPhenomenological Evidence for the Gluon Content of η and η ′
We discuss the effect of η–η mixing and of axial current anomalies on various decay processes. We describe the 2γ decays of η and η, the radiative decays of low-lying vector mesons as well as the decays η → 3π, J/ψ → ηγ and J/ψ → ηγ in one unified framework, in which they are related to the electromagnetic and strong axial current anomalies, respectively. We also discuss briefly the enhancement...
متن کاملPionium Decays and Pion Polarizability
We calculate the decay of pionium atoms into two photons. The pion polariz-ability gives rise to a 10% correction to the corresponding decay width for pointlike pions. This opens the possibility to obtain the polarizability of the charged pion from a future measurement of this decay width if the ππ-scattering lengths are known to better than 5% precision. We also comment on the contribution of ...
