Abstract = {{Using Cu-L-3 edge resonant inelastic x-ray scattering (RIXS) we measured
   the dispersion and damping of spin excitations (magnons and paramagnons)
   in the high-T-c superconductor (Bi,Pb)(2)(Sr,La)(2)CuO6+delta (Bi2201),
   for a large doping range across the phase diagram (0.03 less than or
   similar to p less than or similar to 0.21). Selected measurements with
   full polarization analysis unambiguously demonstrate the spin-flip
   character of these excitations, even in the overdoped sample. We find
   that the undamped frequencies increase slightly with doping for all
   accessible momenta, while the damping grows rapidly, faster in the (0,
   0) -> (0.5, 0.5) nodal direction than in the (0, 0) -> (0.5, 0)
   antinodal direction. We compare the experimental results to numerically
   exact determinant quantum Monte Carlo (DQMC) calculations that provide
   the spin dynamical structure factor S(Q, omega) of the three-band
   Hubbard model. The theory reproduces well the momentum and doping
   dependence of the dispersions and spectral weights of magnetic
   excitations. These results provide compelling evidence that paramagnons,
   although increasingly damped, persist across the superconducting dome of
   the cuprate phase diagram; this implies that long-range
   antiferromagnetic correlations are quickly washed away, while
   short-range magnetic interactions are little affected by doping.}},
