Towards a Unified Model of Neutrino-Nucleus Interactions
Omar Benhar, Camillo Mariani
The achievement of the goals of the ongoing and future accelerator-based neutrino experiments - notably the determination of CP violating phase in the lepton sector - will require…
Crystalline phases by an improved gradient expansion technique
Stefano Carignano, Filippo Anzuini, Omar Benhar +1
We develop an innovative technique for studying inhomogeneous phases with a spontaneous broken symmetry. The method relies on the knowledge of the exact form of the free energy in…
Effect of the cross-section uncertainties on an analysis of neutrino oscillations
Artur M. Ankowski, Omar Benhar, Camillo Mariani +1
We report the results of a study aimed at quantifying the impact on the oscillation analysis of the uncertainties associated with the description of the neutrino-nucleus cross sect…
Comparison of the calorimetric and kinematic methods of neutrino energy reconstruction in disappearance experiments
Artur M. Ankowski, Omar Benhar, Pilar Coloma +5
To be able to achieve their physics goals, future neutrino-oscillation experiments will need to reconstruct the neutrino energy with very high accuracy. In this work, we analyze ho…
Confronting electron- and neutrino-nucleus scattering
Omar Benhar
The analysis of the sample of charged current quasi elastic events collected by the MiniBooNE Collaboration suggests that the scheme successfully employed to describe electron-nucl…
Impact of nuclear effects on the determination of the nucleon axial mass
Omar Benhar, Davide Meloni
We analize the influence of nuclear effects on the determination of the nucleon axial mass from nuclear cross sections. Our work is based on a formalism widely applied to describe…
Inclusive electron spectrum in the region of pion production in electron-nucleus scattering and the effect of the quasi-elastic interaction
Hiroki Nakamura, Tadaaki Nasu, Makoto Sakuda +1
We have carried out a calculation of the inclusive electron scattering cross section off oxygen in the kinematical region corresponding to beam energies between 700 and 1200 MeV, w…
Total neutrino and antineutrino nuclear cross sections around 1 GeV
Omar Benhar, Davide Meloni
We investigate neutrino-nucleus interactions at energies around 1 GeV. In this regime, the main contributions to the cross sections come from quasi-elastic and production proce…
Estimates of the uncertainties associated with models of the nucleon structure functions in the production region
Omar Benhar, Davide Meloni
Theoretical studies of the inclusive electron-nucleus cross section at beam energies up to few GeV show that, while the region of the quasi-elastic peak is understood at quantitati…
Final state interactions in the electroweak nuclear response
Omar Benhar
I review the description of the electroweak nuclear response at large momentum transfer within nonrelativistic many-body theory. Special consideration is given to the effects of fi…
Lepton-nucleus scattering in the impulse approximation regime
O. Benhar, N. Farina, H. Nakamura +2
We discuss theoretical calculations of electron- and neutrino-nucleus scattering, carried out using realistic nuclear spectral functions and including the effect of final state int…
Electron- and neutrino-nucleus scattering in the impulse approximation regime
Omar Benhar, Nicola Farina, Hiroki Nakamura +2
A quantitative understanding of the weak nuclear response is a prerequisite for the analyses of neutrino experiments such as K2K and MiniBOONE, which measure energy and angle of th…
Q**2-dependence of semi-inclusive electron-nucleus scattering and nucleon-nucleon correlations
O. Benhar, S. Fantoni. G. I. Lykasov, N. V. Slavin
We analize semi-inclusive electron-nucleus processes e+A->e'+h+X at moderate Q**2 and energy transfer nu. Our results show that nucleons bound in the nuclear medium are distributed…
Can a Highly Virtual Nucleon Experience Final State Interactions in Electron-Nucleus Scattering?
O. Benhar, S. Liuti
We discuss how the virtuality of the struck particle may affect the final state interactions in electron-nucleus scattering. The extent to which short range correlations inhibit re…
