Subleading corrections to parity-violating pion photoproduction
Light photons meson photovoltaic coupling
2014/12/22
We compute the photon asymmetry Bγ for near threshold parity-violating (PV) pion photoproduction through subleading order. We show that subleading contributions involve a new combination of PV couplin...

Asymmetry of real - photon resonance asymmetric nonzero coupling dynamic hadron p-wave mystery hyperon in violation of the o 'hara theorem of weak radiation hyperon decay
2014/12/22
We analyze the real-photon asymmetry Aγ± for the parity-violating (PV) π± production on the Δ resonance via the reactions γ⃗+p→Δ+→π++n and γ⃗+d→Δ0+p→π-+p+p. This asymmetry is nonvanishing ...

Have been analyzed the latest experimental data for $\gamma + p \to K^{+} + \Lambda$ reaction of $C_{x'}$ and $C_{z'}$ double polarizations. In theoretical calculation, all of these observables can be...

2010/12/29
We demonstrate that the Dubna-Mainz-Taipei (DMT) meson-exchange dynamical model, which starts from an effective chiral Lagrangian, for pion photoproduction provides an excellent and economic framework...
