Abstract: (APS)
New data on the reaction νp→μ−Δ++ are compared with theoretical predictions. We stress the importance of the Δ spin-density matrix in making decisive tests of the models. The data are consistent with the prediction using partially conserved axial-vector currents for dσdq2 near q2=0. In contrast to previous findings, Adler's relativistic version of the static model is reasonably successful in fitting the data. Zucker's model also fits the data.- neutrino p: interaction
- interaction: neutrino p
- final state
- delta(1236)
- spin: density matrix
- density matrix: spin
- current algebra
- PCAC model
- model: zucker
- neutrino: total cross section
