Abstract

We report angle-resolved photoemission results on high-Tc superconductor La1.85Sr0.15CuO4. 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.
