Isolating vector boson scattering at the CERN LHC: Gauge cancellations and the equivalent vector boson approximation versus complete calculations

Year: 2006

Type: article

Abstract: We have studied the possibility of extracting the ${W}^{+}{W}^{\ensuremath{-}}\ensuremath{\rightarrow}{W}^{+}{W}^{\ensuremath{-}}$ signal using the process $us\ensuremath{\rightarrow}cd{W}^{+}{W}^{\ensuremath{-}}$ as a test case. We have investigated numerically the strong gauge cancellations between signal and irreducible background, critically analyzing the reliability of the equivalent vector boson approximation which is commonly used to define the signal. Complete matrix elements are necessary to study electroweak symmetry breaking effects at high $WW$ invariant mass.
