Precision Electroweak Measurements With The Cms Detector

Recent results by the CMS experiment on Drell-Yan, W and multiboson events are presented, including in particular the measurement of the electroweak mixing angle, the differential distributions in Drell-Yan events, and the electroweak production of one and two vector bosons in association with two jets. No deviations from the Standard Model predictions are found and stringent bounds are set on anomalous triple and quartic gauge couplings.
