Abstract

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^-1of proton-proton collision data at a center-of-mass energy of s=8TeV 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_Tand ω_Tstates 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.
