Abstract
The spectrum and the factorizable S-matrices of the massive excitations of the phi-1,2 deformation of the nonunitary minimal models M2,2n + 1 is given. These models present no kinks as asymptotic states, as follows from the reduction of the Zhiber-Mikhailov-Shabat model with respect to the quantum group SL(2) q, found by Smirnov. An interesting situation of zeros and poles overlapping in the physical amplitudes is also discussed.File in questo prodotto:
