Abstract:
We present a real-space renormalization-group analysis for Z2 lattice gauge theory coupled to a Higgs field in four dimension,the results show a phase diagram in which the Higgs and confined region are smoothly connected.

Abstract:
A correct relativistic nuclear model is presented on the ratios of structure functions FA(x,Q2) measured in DIS with several different nuclei.We shall assume here that a nucleus consists of nucleons,antinucleons and excess pions,the pions being assoc...
