摘要：

We re-evaluate our model predictions in Phys. Rev. D 79, 013002 (2009) for different observables in neutrino induced coherent pion production. This comes as a result of the new improved fit to old bubble chamber data of the dominant axial C-5(A) nucleon-to-Delta form factor. We find an increase of 20%similar to 30% in the values for the total cross sections. Uncertainties induced by the errors in the determination of C-5(A) are computed. Our new results turn out to be compatible within about 1 sigma with the former ones. We also stress the existing tension between the recent experimental determination of the sigma(CCcoh pi(+))/sigma(NCcoh pi(0)) ratio by the SciBooNE Collaboration and the theoretical predictions.
