We present a study of coherent pion production in neutrino-nucleus interactions using the formalism based on partially conserved axial current theorem which connects cross section to pion-nucleus elastic scattering section. Pion-nucleus is calculated Glauber model takes three inputs, nuclear densities, pion-nucleon and $\alpha_{\pi N}$ ratio real imaginary part $\pi N$ forward amplitude, for pa...

A detailed study of the effect of the η-nucleus final state interaction (FSI) in the p d → He η reaction close to threshold is presented. The FSI is incorporated through a T-matrix for η He elastic scattering, constructed using few body equations. This T-matrix accounts for off-shell and binding effects in η-nucleus scattering. The energy dependence of the data on the p d → He η reaction near t...

A bstract For a class of macroscopic dark matter models, inelastic scattering off nucleus can generate electromagnetic signatures with GeV-scale energy. The IceCube detector, its kilometer-scale size, is ideal for directly detecting such scattering. Based on the slow particle trigger DeepCore we perform detailed signal and background simulation to estimate discovery potential. order 1 GeV depos...

The theory of high-energy hadron-nucleus collisions is discussed by means of the multiple-diffraction theory. Effects of the Coulomb field are accounted for in elastic scattering by light and heavy nuclei. Inelastic scattering is treated by means of the shadowed single collision approximation at small momentum t rans fer and the corresponding multiple collision expansion at large momentum t r a...

We calculate LSP-nucleus elastic scattering cross sections using some representative input in the restricted SUSY parameter space. The coherent matrix elements are computed throughout the periodic table while the spin matrix elements for the proposed Pb target which has a rather simple nuclear structure. The results are compared to those given from other cold dark matter detection targets. 1 Pr...

We derive the contribution of ∆-h excitations to quasielastic charged-current neutrino-nucleus scattering in the framework of relativistic mean-field theory. We discuss the effect of ∆ production on the determination of the axial mass MA in neutrino scattering experiments.

We investigate theoretical approaches to pion–nucleus elastic scattering at high energies (300 ≤ Tπ ≤ 1 GeV). A “model–exact” calculation of the lowest–order microscopic optical model, carried out in momentum space and including the full Fermi averaging integration, a realistic off–shell pion–nucleon scattering amplitude and fully covariant kinematics, is used to calibrate a much simpler theory...

High-precision studies of Beyond-Standard-Model physics through accelerator-based neutrino oscillation experiments require a very accurate description neutrino–nucleus cross-sections in broad energy region, going from quasielastic scattering up to deep, inelastic scattering. In this work, we focus on the following processes: scattering, two-particle-two-hole excitations, and excitation first (D...
