Parity nonconserving asymmetries in the resonance scattering and nuclear reactions involving polarized protons

The parity nonconserving nucleon-nucleon (PNC-NN) interaction studied in nuclear systems provides a unique window on ΔS=0 hadronic weak processes. To check the predictions concerning the interaction between weak hadronic currents, low energy nuclear physics processes appear to be very suitable. Considering the nuclear reactions induced by polarized protons as low energy nuclear processes we derive expressions for the longitudinal and the irregular transverse PNC analyzing powers, when the reactions take place via parity mixed resonances. Applications for 13C(p,p)13C, 15N(p,p)15N and 15N(p,α)12C resonance reactions are done.(authors)
