Abstract

The boundary conditions with diagonal boundary S matrix and the boundary form factors for the Smirnov--Fateev model on a half line has been considered in the framework of the free field representation. In contrast to the case of the sine-Gordon model, in this case the free field representation is shown to impose severe restrictions on the boundary S matrix, so that a finite number of solutions is only consistent with the free field realization.
