Abstract / Description of output

A search for physics beyond the Standard Model inducing periodic signals in
the dielectron and diphoton invariant mass spectra is presented using 139 fb−1 of √s = 13 TeV pp collision data collected by the ATLAS experiment at the LHC. Novel search techniques based on continuous wavelet transforms are used to infer the frequency of periodic signals from the invariant mass spectra and neural network classifiers are used to enhance the sensitivity to periodic resonances. In the absence of a signal, exclusion limits are placed at the 95% confidence level in the two-dimensional parameter space of the clock-work gravity model. Model-independent searches for deviations from the background-only hypothesis are also performed.
