Decay of particles above threshold in the Ising field theory with magnetic field
G. Delfino, P. Grinza, G. Mussardo
The two-dimensional scaling Ising model in a magnetic field at critical temperature is integrable and possesses eight stable particles A_i (i=1,...,8) with different masses. The he…

Random Bond Ising Model and Massless Phase of the Gross-Neveu Model
G. Mussardo, P. Simonetti
The Gross-Neveu model for presents a massless phase that can be characterized by right-left mover scattering processes. The limit $n \goto 0$ describes the on-shell…

Statistical Models with a Line of Defect
G. Delfino, G. Mussardo, P. Simonetti
The factorization condition for the scattering amplitudes of an integrable model with a line of defect gives rise to a set of Reflection-Transmission equations. The solutions of th…
