Title: Â Towards More Precise Examinations of the Standard Model
Abstract:  After the first two successful runs of the CERN LHC, experimental collaborations, such as CMS Collaboration, have collected and analyzed quadrillions of high energy proton-proton collisions and produced an extensive suite of physics results. Our understanding of the physics processes, detector interactions, and reconstruction algorithms has been significantly improved. With the ongoing Run 3 and upcoming HL-LHC runs, the amount of data is expected to increase by another order of magnitude. This allows us to carry out standard model measurements with unprecedented precision, but also brings challenges in areas such as reconstruction and computing. In this talk, I will take the study of W boson properties as an example, focusing on the cross section measurements, and show how much we can reduce the measurement systematic uncertainties and push the precision of the Standard Model. I will also briefly discuss how we can improve these studies and meet the upcoming challenges with modern tools such as machine learning.
