Constraints on additional Z' gauge bosons from a precise measurement of the Z mass

# metadata.dc.description.abstract[].value
We analyze the constraints on the mass and mixing of a superstring-inspired E6 Z' neutral gauge boson that follow from the recent precise Z mass measurements and show that they depend very sensitively on the assumed value of the W mass and also, to a lesser extent, on the top-quark mass.
