Three Jet Events and New Strong Couplings at LEP and NLC

Abstract

We study the effects of new dimension--6 operators, resulting from a general $SU(3{)}_C\otimes SU(2{)}_L\otimes U(1{)}_Y$ invariant effective Lagrangian, on three jet production at LEP and at the Next Linear Collider. Contributions to the total event rate and to some event shape variables are analysed in order to establish bounds on these operators.
