Abstract

The cross section for WW production is measured and limits on anomalous WWγ and WWZ trilinear gauge couplings are set using WW → ee/eμ/μμ events collected by the Run II D0 detector at the Fermilab Tevatron Collider corresponding to 1 fb^-1 of integrated luminosity at √s = 1.96 TeV. Across the three final states, 108 candidate events are observed with 40.8± 3.8 total background expected, consistent with σ(p$$\bar{p}$$ → WW) = 11.6 ± 1.8(stat) ± 0.7(syst) ± 0.7(lumi) pb. Using a set of SU(2)_L Ⓧ U(1)_Y conserving constraints, the one-dimensional 95% C.L. limits on trilinear gauge couplings are -0.63 < Δκ_γ< 0.99, -0.15 < Λ_γ < 0.19, and -0.14 < Δg₁^Z < 0.34.

Limits on anomalous trilinear gauge couplings from WW{yields}e{sup +}e{sup -}, WW{yields}e{sup {+-}}{mu}{sup {+-}}, and WW{yields}{mu}{sup +}{mu}{sup -} events from pp collisions at {radical}(s)=1.96 TeV

Journal Article Abazov, V; Alexeev, G; Kalinin, A; ... - Physical Review. D, Particles Fields

Limits are set on anomalous WW{gamma} and WWZ trilinear gauge couplings using W{sup +}W{sup -}{yields}e{sup +}{nu}{sub e}e{sup -}{nu}{sub e}, W{sup +}W{sup -}{yields}e{sup {+-}}{nu}{sub e}{mu}{sup {+-}}{nu}{sub {mu}}, and W{sup +}W{sup -}{yields}{mu}{sup +}{nu}{sub {mu}}{mu}{sup -}{nu}{sub {mu}} events. The data set was collected by the Run II D0 detector at the Fermilab Tevatron Collider and corresponds to approximately 250 pb{sup -1} of integrated luminosity at {radical}(s)=1.96 TeV. Under the assumption that the WW{gamma} couplings are equal to the WWZ couplings and using a form factor scale of {lambda}=2.0 TeV, the combined 95% C.L. one-dimensional coupling limits from all three channels are -0.32<{delta}{kappa}<0.45 andmore » -0.29<{lambda}<0.30.« less

Search for anomalous WW/WZ → evjj production at D0; Busqueda de produccion anomala WW/WZ →evjj en D-Zero (in English;Spanish)

Thesis/Dissertation Hernandez, Alberto

A search for anomalous WW and WZ production in p$$\bar{p}$$ collisions at √s = 1.8 TeV using the D0 detector at Fermilab is presented. With a data sample of p$$\bar{p}$$ → evjjX events corresponding to an integrated luminosity of 76.5 ± 4.1pb^-1. 399 candidate events were identified, from which 387.1 ± 39.8 events were estimated to be background. No deviations from the Standard Model were seen, which predicts 16.2 ± 2.7 events. The 95% CL limit on the cross section σ(p$$\bar{p}$$ → W⁺W^-X) was calculated to be 93.8 pb.

Measurement of the WW Production Cross Section with Dilepton Final States in pp Collisions at sq root(s)=1.96 TeV and Limits on Anomalous Trilinear Gauge Couplings

Journal Article Abazov, V; Alexeev, G; Kharzheev, Y; ... - Physical Review Letters

We provide the most precise measurement of the WW production cross section in pp collisions to date at a center of mass energy of 1.96 TeV, and set limits on the associated trilinear gauge couplings. The WW->lnul{sup '}nu (l, l{sup '}=e, mu) decay channels are analyzed in 1 fb{sup -1} of data collected by the D0 detector at the Fermilab Tevatron Collider. The measured cross section is sigma(pp->WW)=11.5+-2.1(stat+syst)+-0.7(lumi) pb. One- and two-dimensional 95% C.L. limits on trilinear gauge couplings are provided.

We provide the most precise measurement of the WW production cross section in p{bar p} collisions to date at a center of mass energy of 1.96 TeV, and set limits on the associated trilinear gauge couplings. The WW {yields} {ell}{nu}{ell}{prime}{nu} ({ell},{ell}{prime} = e,{mu}) decay channels are analyzed in 1 fb{sup -1} of data collected by the D0 detector at the Fermilab Tevatron Collider. The measured cross section is {sigma}(p{bar p} {yields} WW) = 11.5 {+-} 2.1 (stat + syst) {+-} 0.7 (lumi) pb. One- and two-dimensional 95% C.L. limits on trilinear gauge couplings are provided.
A Meaurement of the W⁺ W^- production cross section in p$$\bar{p}$$ collisions at √s=1.96 TeV in the DiLepton channel and limits on anomalous WWZ/γ couplings

Thesis/Dissertation McGivern, Dustin

Measurements of the production cross section of W⁺ W^- pairs in p$$\bar{p}$$ collisions at 1.96 TeV and limits on trilinear gauge boson coupling (TGC) parameters are presented. The data were recorded with the CDF experiment at Tevatron during the 2001 and 2002 data taking periods in which a total integrated luminosity of 184 pb^-1 was collected. The data sample was filtered for events with two leptonic w boson decays where the charged leptons can be either electrons or muons. 17 events are observed against an expected background of 5.0$$+2.2\atop{-0.8}$$ events. The resulting cross-section is found to be σ(p$$\bar{p}$$ → W⁺more »« less
