A product system E over a semigroup P is a family of Hilbert spaces [E s : s # P] together with multiplications E s \_E t ร E st . We view E as a unitary-valued cocycle on P, and consider twisted crossed products A < ;, E P involving E and an action ; of P by endomorphisms of a C\*-algebra A. When P

By the method of cyclic cohomology we prove that all tracial states on a twisted group \(C^{*}\)-algebra \(C^{*}(G ; \sigma)\), where \(G\) is a torsion free discrete group of polynomial growth and \(\sigma\) is a 2-cocycle on \(G\) with values in the unit circle group, induce the same map from \(K_
