[en] A unified treatment of the lambda phi4 theory in any number of dimensions (ν) is given, within the scheme of dimensional regularization. Use is made of the Gaussian approximation and a comparison with the one-loop effective potential is given in different dimensions. For fixed renormalized quantities, there are cases (in particular for ν → 4) for which the bare parameters go to zero. Nevertheless the corrections (Gaussian or perturbative) are such that the final results are finite

[en] It is shown that the Skyrme force is not adapted for the study of pion-condensed nuclear systems where the nucleons have a particular spin-isospin structure

[en] Using the Hartree-Fock method with the Skyrme effective interaction, a set of parameters is found, which both provides a fair description for the atomic nuclei existing in reality and admits the existence of highly neutron-rich nuclei with A/Z<=15. The stability boundaries with respect to the nucleon emission are also calculated with account for the new interaction. Regions of neutron-rich nuclei are found

[en] in this paper the optimal unitarity lower bound on logarithmic slope of the diffraction peak is investigated. It is shown that the unitarity lower bound is just the optimal logarithmic slopes predicted by the principle of least distance in space of states. A systematic tendency towards the saturations of the most forward-peaked limit is observed from all the available experimental data of all principal hadron-hadron scatterings (e.g., PP, P bar P, K±P, π±P) practically at all laboratory momenta.
