In contrast to a complex feature of antinodal state, suffering from competingorder(s), the "pure" pairing gap of cuprates is detected in the nodal region,which therefore holds the key to the superconducting mechanism. The pairing gaphas been viewed to be rather conventional, closing at the superconductingtransition temperature (Tc). However, the density of states contributed fromthe nodal region was claimed to have a gap-like structure even above Tc. Herewe present a missing evidence for a single-particle gap near the nodesignifying the realization of a phase incoherent d-wave superconductivity aboveTc in the optimally doped Bi2Sr2CaCu2O8+d. We find that the pair formation isformulated by momentum-independent temperature evolutions of three parameters:a BCS-type energy gap (Delta), a single particle scattering rate (Gamma_single)and a pair breaking rate (Gamma_pair). The superconductivity occurs when theGamma_pair value is suppressed smaller than Gamma_single on cooling, and themagnitude of Tc in cuprates is governed by a condition ofGamma_single(Tc)=Gamma_pair(Tc).
