\n Resonant inela stic x-ray scattering (RIXS) has emerged as a powerful tool for studying h igh-temperature superconducting materials. In the talk\, I will show how a theory based on non-interacting quasi-particles can describe recent exper imental data on optimally doped and overdoped YBa2Cu3O6+x \;[Minola&nb sp\;et al.\, Phys. Rev. Lett. \;114\, 217003 (2015)]. Surprisingly\, the RIXS signal is qualitatively different from t hose measured using a different cuprate material\, Bi2Sr2CuO6+x \;[Gua rise \;et al.\, Nat. Commun. \;5\, 5760 (2014)]\, a feature originally attributed to collective magnetic excitatio ns. I will demonstrate that this discrepancy can be explained by the sensi tivity of RIXS to details of the band structures of these materials\, espe cially \;at energies well above the Fermi surface. This energy range i s \;inaccessible to traditionally used band structure probes\, such as angle-resolved photemisson spectroscopy\, making RIXS a powerful band str ucture probe\, potentially applicable to a wide range of materials.
