The R-matrix of the Uq(d4(3)) algebra and g2(1) affine Toda field theory
Abstract
The R-matrix of the Uq(d4(3)) algebra is constructed in the 8-dimensional fundamental representation. Using this result an exact S-matrix is conjectured for the imaginary coupled g2(1) affine Toda field theory, the structure of which is found to be very similar to the previously investigated S-matrix of d4(3) Toda theory. It is shown that this S-matrix is consistent with the results for the case of real coupling using the breather-particle correspondence. For q a root of unity it is argued that the theory can be restricted to yield Phi(11|12) perturbations of WA2 minimal models.
