Title: Subleading corrections to parity-violating pion photoproduction

Journal Article · · Physical Review C
OSTI ID:839243

We compute the photon asymmetry B{sub {gamma}} for near threshold parity violating (PV) pion photoproduction through sub-leading order. We show that sub-leading contributions involve a new combination of PV couplings not included in previous analyses of hadronic PV. We argue that existing constraints on the leading order contribution to B{sub {gamma}}--obtained from the PV {gamma}-decay of {sup 18}F--suggest that the impact of the subleading contributions may be more significant than expected from naturalness arguments.
