Correlation functions of the composite field T\bar{T} 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 T\bar{T} 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.
