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, V gamma, with V = W(-{\textgreater} l nu) or Z(-{\textgreater} l(+)l(-)), where l = mu or mu. The measurements use 20.3fb(-1) of proton-proton collision data at a center-of-mass energy of root 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(T) and omega(T) states of a benchmark Low Scale Technicolor model are excluded in the ranges [275, 960] {GeV} and [200, 700]boolean {OR}[750, 890] {GeV}, respectively. Limits at 95\% confidence level on the production cross section of a singlet scalar resonance decaying to Z gamma final states have also been obtained for masses below 1180GeV.
