We construct P()1-processes indexed by the full time-line, separately derived from thefunctional integral representations of the classical Nelson model and relativistic Nelsonmodel in quantum eld theory. Associated with these processes we dene a martingalewhich, under proper scaling, allows to obtain a central limit theorem for additive functionalsof the two processes. We show a number of examples by choosing specic functionalsrelated to particle-eld operators.
