This work reports on high-resolution inelastic X-ray scattering experiments revealing a striking renormalization of the phonon spectra of high-Tc cuprates associated with the formation of charge density waves. Their origin is attributed to the hybridization of phonons with dispersive collective excitations of the charge density waves, providing insights in the role of electron-phonon interaction in high temperature superconductors.
