“…The full model calculations show an excellent agreement with the data [30] for the nπ + final state. At high E ′ , corresponding to the invariant mass region below the Delta resonance, we observe a noticeable increase of the cross section in comparison with the Delta pole diagram, which significantly improves the agreement with the data.…”

One pion production in neutrino reactions: Including nonresonant background

et al. 2010

View full text Add to dashboard Cite

We investigate neutrino induced one pion production on nucleons. The elementary neutrinonucleon cross section is calculated as the sum of the leading Delta pole diagram and several background diagrams obtained within the nonlinear sigma model. This approach does not introduce any new adjustable parameters, which allows unambiguous predictions for the observables. Considering electroproduction experiments as benchmark, the model is shown to be applicable up to pion-nucleon invariant mass W < 1.4 GeV and provides a good accuracy. With respect to the total one pion cross section, the model predicts the background at the level of 10% for the pπ + , 30% for pπ 0 , and 50% for nπ + final states. The results are compared with experimental data for various differential cross sections. Distributions with respect to muon-nucleon and muon-pion invariant masses are presented for the first time. The model describes the data quite well, with the discrepancies being of the same order as those between different data sets.

“…Actually, there is no significant difference between this recent parametrization and the most traditional one of Refs. [56][57][58] in the range of momentum transfer considered in this work (q < 4 fm −1 ). In the present work, in addition to PWBA, we also perform DWBA calculations solving the Dirac equation which contains the central potential arising from the proton ground-state distribution.…”

Charge and matter distributions and form factors of light, medium, and heavy neutron-rich nuclei

et al. 2005

View full text Add to dashboard Cite

Results of charge form factors calculations for several unstable neutron-rich isotopes of light, medium, and heavy nuclei (He, Li, Ni, Kr, Sn) are presented and compared to those of stable isotopes in the same isotopic chain. For the lighter isotopes (He and Li) the proton and neutron densities are obtained within a microscopic large-scale shell-model, while for heavier ones Ni, Kr, and Sn the densities are calculated in deformed self-consistent mean-field Skyrme HF+BCS method. We also compare proton densities to matter densities together with their rms radii and diffuseness parameter values. Whenever possible comparison of form factors, densities and rms radii with available experimental data is also performed. Calculations of form factors are carried out both in plane wave Born approximation (PWBA) and in distorted wave Born approximation (DWBA). These form factors are suggested as predictions for the future experiments on the electron-radioactive beam colliders where the effect of the neutron halo or skin on the proton distributions in exotic nuclei is planned to be studied and thereby the various theoretical models of exotic nuclei will be tested.

Threshold 3He and 3H Transverse Electron Scattering Response Functions

et al. 2009

View full text Add to dashboard Cite

The threshold transverse response functions R T (q, ω) for 3 He and 3 H are calculated using the AV18 nucleon-nucleon potential, the UrbanaIX three-body force, and the Coulomb potential. Final states are completely taken into account via the Lorentz integral transform technique. Consistent two-body π-and ρ-meson exchange currents as deduced using the Arenhövel-Schwamb technique are included. The convergence of the method is shown and a comparison of the corresponding MEC contribution is made to that of a consistent MEC for the meson theoretical r-space BonnA potential. The response R T is calculated in the threshold region at q=174, 324, and 487 MeV/c and compared with available data. The strong MEC contributions in the threshold region are nicely confirmed by the data at q=324 and 487 MeV/c although some differences between theoretical and experimental results remain. A comparison is also made with other calculations, where the same theoretical input is used. The agreement is generally rather good, but leaves also some space for further improvement.
