Data: | 2014 | Editora: | Elsevier | Título da revista, periódico, livro ou evento: | Physics Letters, Section B: Nuclear, Elementary Particle and High-Energy Physics | Volume: | 738 | Resumo: | 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. | URI: | https://hdl.handle.net/10316/109631 | DOI: | 10.1016/j.physletb.2014.10.002 | Direitos: | openAccess |
