Search for new resonances in W γ and Zγ final states in pp collisions at √s = 8TeVwith 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) or Z (→ ℓ+ℓ-), where ℓ = e or μ . The measurements use 20.3 fb<sup>-1</sup> of proton–proton collision data...

| Sumario: | 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) or Z (→ ℓ+ℓ-), where ℓ = e or μ . The measurements use 20.3 fb<sup>-1</sup> 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 aT and ωT 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. |
