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 clockwork gravity model. Model-independent searches for deviations from the background-only hypothesis are also performed. %K Beyond Standard Model %K Hadron-Hadron Scattering %K Particle and Resonance Production %R 10.1007/JHEP10(2023)079 %U https://arxiv.org/abs/2305.10894 %U https://doi.org/10.1007/JHEP10(2023)079 %P 079-51pp
