Abstract
The authors present a comprehensive study of superconducting pairing in the one-band Hubbard model. By comparing different theoretical techniques, the paper shows that the hierarchy of pairing instabilities evolves smoothly from weak- to strong coupling. Additionally, the doping-dependence of the leading superconducting instability is mapped out, and found to be in agreement with previous theoretical studies of the one-band Hubbard model.
