From tree- to loop-simplicity in affine Toda theories I: Landau singularities and their subleading coefficients
Abstract Various features of the even order poles appearing in the S-matrices of simply-laced affine Toda field theories are analysed in some detail. In particular, the coefficients of first- and second-order singularities appearing in the Laurent expansion of the S-matrix around a general 2N th ord...
