Search for anomalous quartic WW{\gamma}{\gamma} couplings in dielectron and missing energy final states in ppbar collisions at sqrt(s) = 1.96 TeV

Understand

We present a search for anomalous components of the quartic gauge boson coupling WW{\gamma}{\gamma} in events with an electron, a positron and missing transverse energy.

• The analyzed data correspond to 9.7 fb^-1 of integrated luminosity collected by the D0 detector in ppbar collisions at sqrt(s) = 1.96 TeV.
• The presence of anomalous quartic gauge couplings would manifest itself as an excess of boosted WW events.
• No such excess is found in the data, and we set the most stringent limits to date on the anomalous coupling parameters a_0^W and a_C^W.
