This analysis, combined with a previous study of 36 \\fbinv of 2016 data (totaling 137 \\fbinv), reveals no significant deviations from standard model expectations. The results are then used to establish 95% confidence level limits on parameters in theoretical models involving dark matter and large extra dimensions. Compared to the 2016-only analysis, this search achieves up to a 14% improvement in exclusion reach for mediator masses in simplified dark matter models, along with 11% and 10% enhancements in the limits on the effective field theory suppression scale and the fundamental Planck scale, respectively. These results are the most stringent constraints on these parameters to date in the monophoton final state.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.166403.v2/t1","@type":"Dataset","description":"Distribution of ET /pmiss for the 2017 data sets.","name":"Figure 2
