Search for new resonances in Wγ and Zγ final states in pp collisions at √s = 8 TeV with the ATLAS detector
This Letter presents a search for new resonances decaying to final states with a vector boson produced in association with a high transverse momentum photon, Vγ, with V=W(→ℓν)V=W(→ℓν) or Z(→ℓ[superscript +]ℓ[superscript −]), where ℓ=e or μ . The measurements use 20.3 fb[superscript −1] of proton–pro...

| description | This Letter presents a search for new resonances decaying to final states with a vector boson produced in association with a high transverse momentum photon, Vγ, with V=W(→ℓν)V=W(→ℓν) or Z(→ℓ[superscript +]ℓ[superscript −]), where ℓ=e or μ . The measurements use 20.3 fb[superscript −1] of proton–proton collision data at a center-of-mass energy of √s = 8 TeV recorded with the ATLAS detector. No deviations from the Standard Model expectations are found, and production cross section limits are set at 95% confidence level. Masses of the hypothetical a[subscript T] and ω[subscript T] states of a benchmark Low Scale Technicolor model are excluded in the ranges [275, 960] GeV and [200,700]∪[750,890] GeV, respectively. Limits at 95% confidence level on the production cross section of a singlet scalar resonance decaying to Zγ final states have also been obtained for masses below 1180 GeV. |
