Abstract |
We report the measurement of muon neutrino charged-current interactions on carbon without pions in the final state at the T2K beam energy using 5.734 x 10(20) protons on target. For the first time the measurement is reported as a flux-integrated, double-differential cross section in muon kinematic variables (cos theta(mu), p(mu)), without correcting for events where a pion is produced and then absorbed by final state interactions. Two analyses are performed with different selections, background evaluations and cross-section extraction methods to demonstrate the robustness of the results against biases due to model-dependent assumptions. The measurements compare favorably with recent models which include nucleon-nucleon correlations but, given the present precision, the measurement does not distinguish among the available models. The data also agree with Monte Carlo simulations which use effective parameters that are tuned to external data to describe the nuclear effects. The total cross section in the full phase space is sigma = (0.417 +/- 0.047(syst) +/- 0.005(stat)) x 10(-38) cm(2) nucleon(-1) and the cross section integrated in the region of phase space with largest efficiency and best signal-over-background ratio (cos theta(mu) > 0.6 and p(mu) > 200 MeV) is sigma = (0.202 +/- 0.036(syst) +/- 0.003(stat)) x 10(-38) cm(2) nucleon(-1). |

Abstract |
We report the first measurement of the flux-averaged cross section for charged current coherent pi(+) production on carbon for neutrino energies less than 1.5 GeV, and with a restriction on the final state phase space volume in the T2K near detector, ND280. Comparisons are made with predictions from the Rein-Sehgal coherent production model and the model by Alvarez-Ruso et al., the latter representing the first implementation of an instance of the new class of microscopic coherent models in a neutrino interaction Monte Carlo event generator. We observe a clear event excess above background, disagreeing with the null results reported by K2K and SciBooNE in a similar neutrino energy region. The measured flux-averaged cross sections are below those predicted by both the Rein-Sehgal and Alvarez-Ruso et al. models. |
