Title: Search for new resonances in Wγ and Zγ final states in pp collisions at √ s = 8 TeV with the ATLAS detector

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 +-), where ℓ=e or μ. The measurements use 20.3 fb -1 of proton–proton collision data at a center–of–mass energy of $$ \sqrt{s}$$=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 α T and ω 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.
