Description
We present measurements of the forward backward asymmetry in the Drell-Yan dilepton events and a study of extracting the weak mixing angle with the data sample of pp collisions at sqrt(s) at 8 TeV collected by CMS in 2012. Thanks to the large data sample, corresponding to about 19/fb, and new techniques, statistical and systematic uncertainties are significantly improved compared with the previous measurement.
