“…The charged current coherent production cross section has been measured at neutrino energies above 7 GeV by several experiments [14][15][16][17][18] and has been found to agree with the standard coherent model developed by Rein and Sehgal. More recent model dependent searches by K2K [19] and SciBooNE [20] at neutrino energies of 0.5-2 GeV suffer from low statistics and reported null results.…”

“…Coherent reactions are controlled by the nucleus form factor and are more forward peaked than incoherent ones. CC coherent pion production has been studied at higher energies in a number of experiments [3,4,5,6,7,8]. The results could be satisfactorily explained by the Rein-Sehgal model [9] which is based on the partially conserved axial current (PCAC) hypothesis [10].…”

We have developed a model for neutrino-induced coherent pion production off nuclei in the energy regime of interest for present and forthcoming neutrino oscillation experiments. It is based on a microscopic model for pion production off the nucleon that, besides the dominant ∆ pole contribution, takes into account the effect of background terms required by chiral symmetry. Moreover, the model uses a reduced nucleon-to-∆ resonance axial coupling, which leads to coherent pion production cross sections around a factor two smaller than most of the previous theoretical estimates. In the coherent production, the main nuclear effects, namely medium corrections on the ∆ propagator and the final pion distortion, are included. We have improved on previous similar models by taking into account the nucleon motion and employing a more sophisticated optical potential. As found in previous calculations the modification of the ∆ self-energy inside the nuclear medium strongly reduces the cross section, while the final pion distortion mainly shifts the peak position to lower pion energies. The angular distribution profiles are not much affected by nuclear effects. Nucleon motion increases the cross section by ∼ 15% at neutrino energies of 650 MeV, while Coulomb effects on charged pions are estimated to be small. Finally, we discuss at length the deficiencies of the Rein-Sehgal pion coherent production model for neutrino energies below 2 GeV, and in particular for the MiniBooNE and T2K experiments. We also predict flux averaged cross sections for these two latter experiments and K2K.

“…ÿ A, is a process in which the neutrino scatters coherently off the entire nucleus with a small energy transfer. Such a process has been measured in a number of experiments [1][2][3][4], providing a test of the partially conserved axial-vector current (PCAC) hypothesis [5]. The existing data agree with the Rein and Sehgal model [6] based on the PCAC hypothesis for neutrino energies from 7 to 100 GeV, while there exists no measurement at lower energies.…”
