Probing trilinear gauge boson interactions via single electroweak gauge boson production at the CERN LHC

We analyze the potential of the CERN Large Hadron Collider (LHC) to study anomalous trilinear vector-boson interactions W + W − γ and W + W − Z through the single production of electroweak gauge bosons via the weak boson fusion processes q q → q q W ( → ℓ ± ν ) and q q → q q Z ( → ℓ + ℓ − ) with ℓ =...

Sumario:We analyze the potential of the CERN Large Hadron Collider (LHC) to study anomalous trilinear vector-boson interactions W + W − γ and W + W − Z through the single production of electroweak gauge bosons via the weak boson fusion processes q q → q q W ( → ℓ ± ν ) and q q → q q Z ( → ℓ + ℓ − ) with ℓ = e or μ . After a careful study of the standard model backgrounds, we show that the single production of electroweak bosons at the LHC can provide stringent tests on deviations of these vertices from the standard model prediction. In particular, we show that single gauge-boson production exhibits a sensitivity to the couplings Δ κ Z , γ similar to that attainable from the analysis of electroweak boson pair production.
