Abstract
It is shown that the scaling operators in the conformal limit of a two -dimensional field theory have massive form factors which obey a simpl e factorisation property in rapidity space. This has been used to iden tify such operators within the form factor bootstrap approach. A sum r ule which yields the scaling dimension of such operators is also deriv ed.
