Abstract = {{The electron-phonon interaction is a major factor influencing the
   competition between collective instabilities in correlated-electron
   materials, but its role in driving high-temperature superconductivity in
   the cuprates remains poorly understood. We have used high-resolution
   inelastic X-ray scattering to monitor low-energy phonons in
   YBa2Cu3O6.(6) (superconducting transition temperature T-c = 61 K), which
   is close to a charge-density-wave (CDW) instability. Phonons in a narrow
   range of momentum space around the CDW ordering vector exhibit extremely
   large superconductivity-induced line-shape renormalizations. These
   results imply that the electron-phonon interaction has sufficient
   strength to generate various anomalies in electronic spectra, but does
   not contribute significantly to Cooper pairing. In addition, a
   quasi-elastic `central peak' due to CDW nanodomains is observed in a
   wide temperature range above and below T-c, suggesting that the gradual
   onset of a spatially inhomogeneous CDW domain state with decreasing
   temperature is a generic feature of the underdoped cuprates.}},
