Abstract: The electroweak theory is an essential component of the Standard Model of particle physics. Precision measurements of electroweak physics observable, through different decay modes and approaches, could not only provide stringent tests on the Standard Model, but also be used to search for new physics indirectly. The LHCb detector is a forward spectrometer in the Large Hadron Collider. Compared to general-purpose detectors, such as the ATLAS and CMS detectors, it covers a unique acceptance region and provides comprehensive and complementary information. Therefore, the data collected by the LHCb detector could provide stringent constraints on the parton distribution functions of the proton, which is also an important input for the global fit of parton distribution functions. For many important measurements, the LHCb results combined with those from ATLAS and CMS experiments could significantly reduce the systematic uncertainty. This talk will provide an overview of the most recent electroweak results from the LHCb experiment.

Menglin Xu is a postdoctoral fellow at the University of Warwick. She got her Ph.D. from the Central China Normal University. She led the first observation of the Xicc++->Xic+pi+ decay and has been deeply involved in electroweak physics research at the LHCb experiment, including measurements of the W and Z boson mass, Z boson production cross-section, Z boson angular coefficients, and the weak mixing angle. She has been awarded the Warwick University Faculty Postdoctoral Prize. She is also involved in LHCb software and hardware development. For her outstanding contributions to LHCb simulation, she received the LHCb Collaboration Early Career Award. Additionally, she has given several plenary talks at international conferences.
