an 2 00 4 Correction of the low energy theorem of γ → 3 π anomaly
نویسنده
چکیده
A generalized Wess-Zumino-Witten anomalous Lagrangian of psedoscalar, vector, and axial-vector fields has been used to study the γ → 3π anomaly. A correction of the low energy theorem of the γ → 3π is found. Both the amplitude A3π(0, 0, 0) and the cross section, σ z , of π+(Z,A) → ππ+(z,A) are calculated. Theoretical values agree well with the data. In this study there is no new adjustable parameter.

The Bjorken-Johnson-Low theorem applied to the γ → γπ process provides us with a rather remarkable asymptotic behaviour for the πγγ vertex. We compare our result with previous QCDinspired estimates and argue that the predicted behaviour is quite consistent with the present data on hadronic J/Ψ decays and ensures the matching of longand short-distance radiative corrections to π → eνe. Anomalies ...

The radiative decays of the pseudoscalar mesons P = (π 0 , η, η ′) are of special interest as they provide an experimental window on the electromagnetic and colour chiral UA(1) anomalies. π 0 → γγ is well described by the electromagnetic UA(1) anomaly under the assumption that π 0 is a Goldstone boson for spontaneously broken chiral symmetry, but the analogous results for η ′ (η) → γγ are compl...

The general formula of the π − p atom strong energy-level shift in the 1s state is derived in the next-to-leading order in the isospin breaking, and in all orders in chiral expansion. Isospin-breaking corrections to the level shift are explicitly evaluated at order p 2 in ChPT. The results clearly demonstrate the necessity to critically reaccess the values of the πN scattering lengths, extracte...

The weak radiative Cabibbo allowed decays D + → ¯ K 0 π + γ and D 0 → K − π + γ with nonresonant Kπ are investigated by relying on the factorization approximation for the nonleptonic weak transitions and the model which combines the heavy quark effective theory and the chiral Lagrangian approach. The dominant contributions to the amplitudes come from the long distance effects. The decay amplitu...
