Parity-violating effects in electroproduction of the Δ(1232) by polarized electrons
Abstract
Parity-violating effects in the (quasi)elastic scattering of longitudinally polarized electrons from spin- 1/2 targets are discussed in the framework of the unified guage theories of weak and electromagnetic interactions. In particular, the R-L asymmetry in electroproduction of the Δ(1232) is studied in considerable detail, taking into account the full spin-32 structure of this resonance. Our results are valid for all values of E and the entire range of Q2. Numerical predictions are given for the standard Weinberg-Salam model at several energies of the electron beam.
