Abstract A measurement of the production cross section of a W boson and a single charm quark using soft electron tagging is presented here. 'Lepton+jets' events are reconstructed from the high PT lepton trigger selection. Approximately 4.3/fb of data is analyzed. Soft electron tagging is used to identify heavy flavor jets. The W+c signal is produced mainly by strange quark-gluon fusion. The signal is evinced through an excess of events in which the charge of the lepton from the W boson decay and the charge of the soft lepton are opposite in sign.
