Phase Structure of the SU(3) Gauge-Higgs System. II Adjoint Higgs

On etudie la structure de phase du modele de Higgs adjoint SU(3) par une simulation de Monte Carlo. On presente les resultats pour une simulation effectuee sur un reseau euclidien a 4 dimensions de taille 3 4 et 6 3 ×3. On trouve une transition de la phase symetrique vers celle brisee

Shrinking nature of diffraction amplitudes due to peripheral inelastic processes

The nature of the diffraction scattering has been discussed in connection with the Regge-type behaviour of the scattering amplitude at high energies (1). In this note we give an intuitive discussion on the shrinking nature due to the one-mesonexchange-dominated inelastic process which is behind these discussions. Let ]~BCD be the partial-wave inelastic amplitude of the quasi-binary process A-kB-~C-kD. The imaginary diffraction amplitude for the elastic process A-kB-+ -~ A + B duc to this inelastic process will be given in the lowest-order approximation as
