Nucleon helicity in pion photoproduction.
Pion-photoproduction data is examined to check for the nucleon-helicity conservation predicted by asymptotic QCD. The differential cross section shows agreement with constituent-counting rules, and polarization data is not in disagreement with conservation of nucleon helicity. However large uncertainties in the polarization measurements do not allow a conclusive statement. The helicity amplitud...
متن کاملCoherent Pion Photoproduction on Deuterium
Differential cross sections of the γd → dπ 0 reaction were measured at photon beam energies between 0.5 and 2.0 GeV over a wide angular range in the CM system. The experiment was performed in Hall B at Jefferson Lab using the CLAS detector. The excitation function, especially at backward CM scattering angles, has been studied with regard to effects due to intermediate on-shell η and ω rescatter...
متن کاملPion photoproduction on the nucleon
The γn → πp and γ p → π+n reactions are essential probes of the transition from meson-nucleon degrees of freedom to quark-gluon degrees of freedom in exclusive processes. The cross sections of these processes are also advantageous, for the investigation of oscillatory behavior around the quark counting prediction, since they decrease relatively slower with energy compared with other photon-indu...
متن کاملMeasurement of the Weak Pion - Nucleon Coupling Constant , h 1 , in Parity - Violating Backward Pion
This proposal describes a measurement of the weak pion-nucleon coupling constant to a high level of accuracy using moderate beam time in a theoretically \clean" process. We propose to measure the parity-violating asymmetry in pion photoproduction o the proton, ~ p! n . This asymmetry is expected to be 2:3 10 , and can be measured to statistical uncertainty of 0:5 10 7 at Je erson Lab in Hall A....
متن کاملSingle Charged Pion Photoproduction from the Nucleon at 11 GeV July 7 , 2006
The γn → πp and γp → π+n reactions are essential and simplest probes of the transition from meson-nucleon degrees of freedom to quark-gluon degrees of freedom in exclusive processes. The cross sections of these processes are also advantageous, for detailed investigation of the possible oscillatory scaling behavior around the (generalized) quark counting rule prediction, since they decrease rela...
