Abstract

In this paper we present a detailed investigation of the form factors of boundary fields of the sinh-Gordon model with a particular type of Dirichlet boundary condition, corresponding to zero value of the sinh-Gordon field at the boundary, at the self-dual point. We follow for this the boundary form factor program recently proposed by Z Bajnok, L Palla and G Takacs (2006 On the boundary form factor program Preprint hep-th/0603171), extending the analysis of the boundary sinh-Gordon model initiated there. The main result of the paper is a conjecture for the structure of all n-particle form factors of the boundary operators ∂x and (∂x)2 in terms of elementary symmetric polynomials in certain functions of the rapidity variables. In addition, form factors of boundary 'descendant' fields have been constructed.
