We define a weighted mu-calculus on finite and infinite words. Hereby, the mu-calculus does not use conjunction and the weights are taken from semirings satisfying certain completeness and continuity properties. For important semirings like distributive complete lattices, the tropical and the probabilistic semiring, we show that the formulas of the conjunction-free weighted mu-calculus define exactly the class of omega-rational formal power series.
