Abstract
This chapter provides a general introduction to physics. The motivation for using the final state is outlined, and the basics of the signature and event selection are presented. The primary backgrounds to events are discussed, and the methods used to estimate them are introduced.

Notes
- 1.
As will be discussed in the following, there is sensitivity to Higgs mass in the transverse mass, which is used to improve the sensitivity of the \(H \rightarrow WW^{(*)}\rightarrow l\nu l\nu \) analysis.
- 2.
This includes the BR of \(W\) to \(\tau \) with the \(\tau \) decaying to an electron or muon.
- 3.
For some reason, unbeknownst to the author, the full jet multiplicity, including the 0-jet bin, is used to define the top control region. In this section the method is described without the 0-jet bin in the top control region. This has the advantage that the MC correction is reduced, and the circularity coming from the overlap with the signal region is avoided. In the Chaps. 10 and 11 the prediction including the 0-jet bin is presented.
