Abstract

We report angle-resolved photoemission results on high-T_c superconductor La_1.85Sr_0.15CuO₄. A sharp Bogoliubov quasiparticle peak and a dispersion kink at 20 meV are observed in the superconducting state at off-nodal region. Present experimental result suggests a coupling between electrons and the incommensurate magnetic resonance.
