Abstract
Correlation functions of the composite field in
the scaling Lee-Yang model are studied. Using the analytic expression for
form factors of this operator recently proposed by
G. Delfino and G. Niccoli, hep-th/0407142 [11bel-DN], we show
numerically that the constraints on the expectation values
obtained in A. B. Zamolodchikov, hep-th/0401146 [11bel-AZ_VEVTT] and
the additional requirement of asymptotic behavior lead to a perfect agreement
with the ultraviolet asymptotic predicted by the conformal perturbation
theory.
