Experimental studies of the endpoint of the superconducting dome for (Bi,Pb)2Sr2CuO6+δ (Bi2201) and La2-xSrxCuO4 (LSCO) have raised questions regarding the nature of the cuprate pairing mechanism. Herein, motivated by these experiments, we examine the results of dynamic cluster approximation (DCA) calculations and find that a spin-fluctuation interaction can provide a framework for understanding this end point behavior.
