Neutral-Current Single $\pi^0$ Production on Argon / Martini, Marco (IPSA, Paris ; LPNHE, Paris) ; Ericson, Magda (IP2I, Lyon ; CERN) ; Chanfray, Guy (IP2I, Lyon)
We interpret the recent MicroBooNE data on neutral-current single production on argon with the hypothesis that this process occurs via Delta excitation. We calculate the flux-integrated total cross section with our RPA-based model which allows for a simultaneous description of Delta-mediated resonant and coherent pion production. [...]

Phase space of electron- and muon-neutrino and antineutrino scattering off nuclei / Martini, M. (LPNHE, Paris ; IPSA, Paris) ; Ericson, M. (IP2I, Lyon ; CERN) ; Chanfray, G. (IP2I, Lyon)
We discuss the electron and muon neutrino and antineutrino double differential cross sections on carbon in the quasielastic as well as in the multinucleon and one pion production channels. By projecting them in the transferred momentum - transferred energy plane and in the neutrino energy - lepton scattering angle plane, as well as by performing simple considerations on the position of the quasielastic and Delta peaks and on their broadening, we explain the surprising dominance of the muon neutrino and antineutrino cross sections over the electron ones in particular kinematical conditions..

The Interrelated Roles of Correlations in the Nuclear Equation of State and in Response Functions: Application to a Chiral Confining Theory / Chanfray, Guy (IP2I, Lyon) ; Ericson, Magda (IP2I, Lyon ; CERN) ; Martini, Marco (IPSA, Paris ; LPNHE, Paris)
We study the role of short-range correlations, as well as pion and rho loops governing long-range RPA correlations, in nuclear matter properties and response functions. We use an adapted formulation of the Brueckner G-matrix approach to generate a pair correlation function satisfying the Beg--Agassi--Gal theorem, providing a natural cutoff to the loop integrals.

Investigation of the MicroBooNE neutrino cross sections on Argon / Martini, M. (IPSA, Paris ; Paris U., VI-VII) ; Ericson, M. (IP2I, Lyon ; CERN) ; Chanfray, G. (IP2I, Lyon)
Experimental data of charged current inclusive neutrino cross sections on argon as a function of different variables have recently appeared. We have compared them to our theoretical approach. [...]

Multinucleon excitations in neutrino–nucleus scattering: connecting different microscopic models for the correlations / Chanfray, G. (IP2I, Lyon) ; Ericson, M. (IP2I, Lyon ; CERN) ; Martini, M. (IPSA, Paris ; Paris U., VI-VII)
The problem of nucleon-nucleon correlations and meson exchange currents has been vividly debated in connection with the neutrino-nucleus cross sections. In this work we focus on nucleon-nucleon correlations by discussing a formal correspondence between the approaches based on independent particles and the ab initio approaches involving correlated wave functions. [...]

$\gamma$ production in neutrino interactions with nuclei / Chanfray, G. (IP2I, Lyon) ; Ericson, M. (IP2I, Lyon ; CERN)
We evaluate the cross-section for gamma production by neutrinos through a meson exchange effect which derives from the concept of axial-vector mixing. The resulting cross-section leads to some increase of the gamma production cross-section by neutrinos, especially at low neutrino energies, which may influence the understanding of the low energy excess of electron-like events seen in the MiniBooNE experiment..

Neutrino-nucleus cross-sections: a unified theoretical approach for nucleon knock-out, coherent and incoherent pion production / Martini, M (CERN ; Bari U. ; Lyon, IPN) ; M. Ericson (Lyon, IPN ; CERN) ; G. Chanfray (Lyon, IPN) ; Marteau, J (Lyon, IPN)
Neutrino-nucleus cross-sections are needed to interpret neutrino oscillation data, as neutrino detectors involve complex nuclei. We present a theory of neutrino interactions with nuclei aimed at a unified description of the partial cross-sections, namely quasi-elastic and multi-nucleon emission, coherent and incoherent single pion production.

Energy reconstruction effects in neutrino oscillation experiments and implications for the analysis / Martini, M. (Brussels U.) ; Ericson, M. (Lyon, IPN ; CERN) ; Chanfray, G. (Lyon, IPN)
Data on neutrino oscillation often involve reconstructed neutrino energies while the analysis implies the real neutrino energy. The corrections corresponding to the transformation from real to reconstructed energy are discussed in the case of Cherenkov detectors where multinucleon events appear as quasielastic ones. [...]

Neutrino energy reconstruction problems and neutrino oscillations / Martini, M. (Brussels U.) ; Ericson, M. (Lyon, IPN ; CERN) ; Chanfray, G. (Lyon, IPN)
We discuss the accuracy of the usual procedure for neutrino energy reconstruction which is based on the quasielastic kinematics. Our results are described in terms of a probability distribution for a real neutrino energy value. [...]
