The analysis uses a data sample with an integrated luminosity of 139 fb$^{-1}$ collected by the ATLAS detector during the 2015-2018 LHC data taking. This process is an important probe of the electroweak symmetry breaking mechanism in the Standard Model and is sensitive to quartic gauge boson couplings via vector-boson scattering. The fiducial $Z(\\nu\\bar{\\nu})\\gamma jj$ cross section for the electroweak production is measured to be 0.75$^{+0.32}_{-0.28}$ fb and is consistent with the Standard Model prediction. Evidence for the electroweak $Z(\\nu\\bar{\\nu})\\gamma jj$ production is found with a significance of 3.2$\\sigma$ in the background-only hypothesis, compared with an expected significance of 3.7$\\sigma$. Combining this result with the previously published ATLAS observation of electroweak $Z(\\nu\\bar{\\nu})\\gamma jj$ production yields in an observed (expected) signal significance of 6.3$\\sigma$ (6.6$\\sigma$). Limits on anomalous quartic gauge boson couplings are obtained in the framework of Effective Field Theory with dimension-eight operators.\n\n\nThe extended fiducial region is defined as:\n - $p_{T}^{\\nu\\bar{\\nu}} >$ 120 GeV\n - $N_{phot}$ = 1\n - $p_{T}^{\\gamma} >$ 150 GeV \n - $|\\eta^{\\gamma}| <$ 2.37\n - $N_{jets} \\geq 2$ \n - $p_{T}^{jet} >$ 50 GeV\n - $|\\eta^{jet}| <$ 4.5\n - $\\Delta R(jet,\\gamma) >$ 0.3\n - $\\Delta\\phi(\\gamma,$p_{T}^{\\nu\\bar{\\nu}})>$ 0.4\n - $\\Delta\\phi(\\jet,$p_{T}^{\\nu\\bar{\\nu}})>$ 0.3\n - $m_{jj}>$300 GeV\n - $\\gamma$-centrality<0.6.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.127924.v1/t1","@type":"Dataset","description":"These graphs indicate the effect of the main theory uncertainties, which are associated with the renormalisation and factorisation scales (dashed...","name":"Table 1"},{"@id":"https://doi.org/10.17182/hepdata.127924.v1/t2","@type":"Dataset","description":"These graphs indicate the effect of the main theory uncertainties, which are associated with the renormalisation and factorisation scales (dashed...","name":"Table 2"},{"@id":"https://doi.org/10.17182/hepdata.127924.v1/t3","@type":"Dataset","description":"The $m_{jj}$ distributions for the CRs and the BDT classifier response distribution for the SR after the fit in all...","name":"Table 3"},{"@id":"https://doi.org/10.17182/hepdata.127924.v1/t4","@type":"Dataset","description":"The $m_{jj}$ distributions for the CRs and the BDT classifier response distribution for the SR after the fit in all...","name":"Table 4"},{"@id":"https://doi.org/10.17182/hepdata.127924.v1/t5","@type":"Dataset","description":"The $m_{jj}$ distributions for the CRs and the BDT classifier response distribution for the SR after the fit in all...","name":"Table 5"},{"@id":"https://doi.org/10.17182/hepdata.127924.v1/t6","@type":"Dataset","description":"The $m_{jj}$ distributions for the CRs and the BDT classifier response distribution for the SR after the fit in all...","name":"Table 6"},{"@id":"https://doi.org/10.17182/hepdata.127924.v1/t7","@type":"Dataset","description":"Observed and expected event yields for the signal and all of the background processes considered in this analysis after the...","name":"Table 7"},{"@id":"https://doi.org/10.17182/hepdata.127924.v1/t8","@type":"Dataset","description":"Summary of the event yield for processes in all regions, after the fit over all regions.
