Absztrakt:
Using the recently introduced boundary form factor bootstrap equations,
the form factors of boundary exponential operators in the sinh-Gordon
model are constructed. We also give a general method to evaluate the
ultraviolet properties of boundary correlators by extending the bulk
cumulant expansion to the boundary case. As an application, the
ultraviolet scaling dimension and the normalization of the operators
corresponding to the form factor solutions are checked against
previously known results for boundary exponential operators. The
construction presented in this paper can be applied to determine form
factors of relevant primary boundary operators in general integrable
boundary quantum field theories. (C) 2008 Elsevier B.V. All rights
