One of the biggest question is whether the point nodal state as a hallmark of <jats:italic>d</jats:italic>-wave pairing collapses at <jats:italic>T</jats:italic><jats:sub>c</jats:sub> like the BCS-type superconductors, or it instead survives above <jats:italic>T</jats:italic><jats:sub>c</jats:sub> turning into the preformed pair state. A difficulty in this issue comes from the small magnitude of the nodal gap, which has been preventing experimentalists from solving it. Here we use a laser ARPES capable of ultrahigh-energy resolution, and detect the point nodes surviving far beyond <jats:italic>T</jats:italic><jats:sub>c</jats:sub> in Bi2212. By tracking the temperature evolution of spectra, we reveal that the superconductivity occurs when the pair-breaking rate is suppressed smaller than the single-particle scattering rate on cooling, which governs the value of <jats:italic>T</jats:italic><jats:sub>c</jats:sub> in cuprates.</jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1380566394948005893","@type":"Researcher","foaf:name":[{"@value":"Takeshi Kondo"}]},{"@id":"https://cir.nii.ac.jp/crid/1380566394948005894","@type":"Researcher","foaf:name":[{"@value":"W.
