“…Adler angle 2 is highly sensitive to the π-iso parameter and has been measured by neutrino induced pion production experiments on single nucleons, such as ANL [42], BNL [43], BEBC [47,48] and FNAL [49]. Nucleon data strongly prefers an anisotropic process, as shown in Fig.…”

Faced with unresolved tensions between neutrino interaction measurements at few-GeV neutrino energies, current experiments are forced to accept large systematic uncertainties to cover discrepancies between their data and model predictions. In this paper, the widely used pion production model in GENIE is compared to four MINERvA charged current pion production measurements using NUISANCE. Tunings, i.e., adjustments of model parameters, to help match GENIE to MIN-ERvA and older bubble chamber data are presented here. We find that scattering off nuclear targets as measured in MINERvA is not in good agreement with expectations based upon scattering off nucleon (hydrogen or deuterium) targets in existing bubble chamber data. An additional ad hoc correction for the low-Q 2 region, where collective nuclear effects are expected to be large, is presented. While these tunings and corrections improve the agreement of GENIE with the data, the modeling is imperfect. The development of these tunings within the NUISANCE framework allows for straightforward extensions to other neutrino event generators and models, and allows omitting and including new data sets as they become available.

We use PCAC in the small Q 2 region in order to calculate the Adler sum rule and the production of hadrons in the low energy region where resonances dominate. We find very good agreement with the sum rule and with the computed cross sections. We find a value C A 5 (0) close to the Goldberger-Treiman prediction. The formalism is general and can be applied to other reactions shedding light into the dynamical transition from resonances to deep inelastic scattering.

“…On the other hand, similar studies on the corresponding weak form factors have been few and far between. In a series of experiments done with intermediate energy neutrinos at ANL, BNL and CERN laboratories, attempts have been made to study the transition form factors for the charge changing weak current, and there exists a fair amount of data to determine these form factors [2][3][4][5][6]. This is not the case with the neutral current processes, where there are very few experiments [7,8] in the intermediate energy range and no serious analysis has been made of the transition form factors.…”

Charged current weak electroproduction of theΔresonance

We study the weak production of ∆ (i.e. e − + p → ∆ 0 + ν e and e + + p → ∆ ++ +ν e ) in the intermediate energy range corresponding to the Mainz and TJNAF electron accelerators. The differential cross sections σ(θ) are found to be of the order of 10 −39 cm 2 /sr, over a range of angles which increases with energy. The possibility of observing these reactions with the high luminosities available at these accelerators, and studying the weak N-∆ transition form factors through these reactions is discussed. The production cross section of N * (1440) in the kinematic region of ∆ production is also estimated and found to be small. 13.60.Rj,13.10+q,25.30.Rw Typeset using REVT E X
