Abstract = {{We used resonant inelastic x-ray scattering (RIXS) with and without
   analysis of the scattered photon polarization, to study dispersive spin
   excitations in the high temperature superconductor YBa2Cu3O6+x over a
   wide range of doping levels (0.1 <= x <= 1). The excitation profiles
   were carefully monitored as the incident photon energy was detuned from
   the resonant condition, and the spin excitation energy was found to be
   independent of detuning for all x. These findings demonstrate that the
   largest fraction of the spin-flip RIXS profiles in doped cuprates arises
   from magnetic collective modes, rather than from incoherent
   particle-hole excitations as recently suggested theoretically
   {[}Benjamin et al. Phys. Rev. Lett. 112, 247002 (2014)]. Implications
   for the theoretical description of the electron system in the cuprates
   are discussed.}},
