Abstract: (Springer)
The phase diagram in the coupling constant in QED and its connection with the spontaneous chiral symmetry breaking are discussed. The mechanism of such a breaking connected with the collapse phenomenon is considered and a simple physical interpretation of the recent results of the computer simulations in lattice QED is given. The problem of the existence of the nontrivial continuum QED is analysed and, as a result, the following hypothesis is considered: in the Landau-Pomeranchuk-Fradkin « zero-charge » situation (the renormalization constantZ3=0) theS-matrix of continuum QED with a fixed bare coupling constant,α(0)=αc∼1, is nontrivial. The physical content of such a hypothetical continuum theory is revealed.- QUANTUM ELECTRODYNAMICS
