Abstract
Here we calculate the pairing interaction and the dependence of the gap function associated with the nematic charge fluctuations of a model. We find that the nematic pairing interaction is attractive for small momentum transfer and that it gives rise to -wave pairing. As the doping approaches a quantum critical point, the strength of this pairing increases and higher -wave harmonics contribute to the dependence of the superconducting gap function, reflecting the longer range nature of the nematic fluctuations.
