An improved model of multiple Dirac eikonal proton scattering, in which amplitudes of elastic pA scattering are found from the Watson multiple scattering series by the eikonal decomposition of the Dirac propagator of free proton motion between scattering events on nucleons, is considered. The structure of the target nucleus is described in the relativistic mean-field models. The calculations of a complete set of observables in the elastic p + 40Ca and p + 208Pb scattering at 800 MeV are carried out, and the effects of the difference between scalar and vector nucleon densities in the description of the observables in p-A scattering are investigated. The amplitude of the Higgs-boson decay to the intermediate neutral Z boson and lepton pair is derived in framework of the effective field theory of the Standard model using the dimension-6 operators. The study of changes in the shape of nuclei in the chains of even-even Kr, Sr, Zr, Mo, and Ru isotopes is carried out based on the relativistic Hartree-Bogoliubov (RHB) model with DD-PC1 and DD-ME2 Lagrangians. The pairing of nucleons is described by a separable pairing interaction. The dependence of the calculated nuclei characteristics on the choice of pairing forces is investigated. The properties of chains of Zr isotopes are investigated using the Hartree-Fock method with the effective Skyrme forces, and pairing is treated in the traditional BCS approximation. The obtained results show that in the vicinity of N = 60 for some Sr, Zr and Mo isotopes, depending on the choice of the pairing force parameters, large jumps in the mean square charge radii and quadrupole deformation parameters are observed.
