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...
Chiral Dynamics and Dubna-Mainz-Taipei Dynamical Model for Pion-Photoproduction Reaction
Chiral Dynamics Dubna-Mainz-Taipei Dynamical Model Pion-Photoproduction Reaction
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...

2009/11/24
We present a preliminary analysis of the photon beam asymmetry observable
(Σ) from the photoproduction reaction channel γn→pπ－ in the invariant mass range 1.6—2.3 GeV. The measurement was obtained us...
Study of Charged Pion Photoproduction on Deuteron with Tagged Photons
deuteron double delta
2009/10/28
The reactions γd→π-pp and γd→npπ+π- have been studied in an energy range from 0.8 to 1.1 GeV at the tagged photon facility of Laboratory of Nuclear Science, Tohoku University. Charged pions and proton...
