Asymptotic factorisation of form factors in twodimensional quantum field theory
Abstract
It is shown that the scaling operators in the conformal limit of a twodimensional field theory have massive form factors which obey a simple factorisation property in rapidity space. This has been used to identify such operators within the form factor bootstrap approach. A sum rule which yields the scaling dimension of such operators is also derived.
