Abstract = {{In the search for the mechanism of high-temperature superconductivity,
   intense research has been focused on the evolution of the spin
   excitation spectrum on doping from the antiferromagnetic insulating to
   the superconducting state of the cuprates. Because of technical
   limitations, the experimental investigation of doped cuprates has been
   largely focused on low-energy excitations in a small range of momentum
   space. Here we use resonant inelastic X-ray scattering to show that a
   large family of superconductors, encompassing underdoped YBa2Cu4O8 and
   overdoped YBa2Cu3O7, exhibits damped spin excitations (paramagnons) with
   dispersions and spectral weights closely similar to those of magnons in
   undoped cuprates. The comprehensive experimental description of this
   surprisingly simple spectrum enables quantitative tests of magnetic
   Cooper pairing models. A numerical solution of the Eliashberg equations
   for the magnetic spectrum of YBa2Cu3O7 reproduces its superconducting
   transition temperature within a factor of two, a level of agreement
   comparable to that of Eliashberg theories of conventional
   superconductors.}},
