“…Single differential electron-neutrino T2K CC inclusive cross sections have been successfully reproduced as well [34]. We have recently shown [35] that the amount of nucleon correlations of our approach is compatible with the one obtained via ab-initio calculations.…”

Experimental data of charged current neutrino cross sections on argon have recently appeared.They are classified in terms of the detected particles, such as one muon (the inclusive cross section) or one muon, zero pion and one single proton (CC0π1p) in the final states. We test our model, which allows a description of different reaction vertices, against the CC0π1p, the CC0πNp and the CC inclusive measurements. For this last channel, a new aspect is the recent availability of data in terms of the energy transfer to the nucleus, which allows a better separation of the different reaction mechanisms. Globally we find a good agreement with data and we explain the deterioration of agreement in specific kinematical conditions by the absence in our model of twopion production and other inelastic channels, more important for MicroBooNE than for T2K. We discuss also the correspondence between the quasielastic vertex and the CC0π1p measurement, as well as the dominance of the multinucleon emission channel in the difference between CC0πNp and CC0π1p data.

The theory of heavy ion double charge exchange (DCE) reactions proceeding by effective rank–2 isotensor interactions is presented. Virtual pion–nucleon charge exchange interactions are investigated as the source for induced isotensor interactions, giving rise to the Majorana DCE (MDCE) reaction mechanism. MDCE is of a generic character, proceeding through pairs of complementary (π±,π∓) reactions in the projectile and target nucleus. The dynamics of the elementary processes is discussed where the excitation of pion–nucleon resonances are of central importance. Investigations of initial and final state ion–ion interactions show that these effects are acting as vertex renormalizations. In closure approximation, well justified by the finite pion mass, the second order transition matrix elements reduce to pion potentials and effective two–body isotensor DCE interactions, giving rise also to two–body correlations in either of the participating nuclei. Connections to neutrinoless Majorana double beta decay (MDBD) are elucidated at various levels of dynamics, from the underlying fundamental electro–weak and QCD scales to the physical scales of nuclear MDBD and MDCE physics. It is pointed out that heavy ion MDCE reactions may also proceed by competing electro–weak charge exchange processes, leading to lepton MDCE by electrons, positrons, and neutrinos.

“…In practice, nuclear ground-state properties are described with Hartree-Fock-Bogolyubov (HFB) theory, and Quasiparticle Random Phase Approximation (QRPA) is used for excited SCE-type states, see [2]. Without going further into the details of the nuclear structure approach, the essence of the approach is that the TMEs, Equation (62), are given by nuclear transition form factors…”
