The superconducting quasiparticle predicted by BCS theory is investigated in a triple-layered high-T_c cuprate Bi₂Sr ₂Ca₂Cu₃O_10+δ, by angle-resolved photoemission spectroscopy (ARPES). We have succeeded in observing the quasiparticle dispersion below and above the Fermi level, and performed a quantitative analysis based on BCS theory. The excellent agreement in the energy dispersion and the coherence factors between the ARPES experiment and BCS theory indicates the basic validity of BCS formalism in describing the superconducting state of cuprates.
