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 $V= W(\rightarrow \ell \nu)$ or $Z(\rightarrow \ell^{+} \ell^{-})$, where $\ell = e$ or $\mu$. The measurements use $20.3$~fb$^{-1}$ of proton--proton collision data at a center--of--mass energy of $\sqrt{s}=8\,\mathrm{TeV}$ 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 $a_{\mathrm{T}}$ and $\omega_{\mathrm{T}}$ states of a benchmark Low Scale Technicolor model are excluded in the ranges $[275,960]\,\mathrm{GeV}$ and $[200,700]\cup[750,890]\,\mathrm{GeV}$, 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 $1180\,\mathrm{GeV}$.
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 −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 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.
