Measurement of the WW Production Cross Section in Proton-Proton Collisions with the ATLAS Detector

A measurement of the W+W− production cross section in pp collisions. The W+W− leptonic decay channels are analysed using data collected by the ATLAS detector at the CERN Large Hadron Collider. The precise measurement of W+W- production is an important to compare observation with the Standard Model expectation, but also to provide a detailed understanding of this process in searches for phenomena to which W+W- production is a background.
