Abstract / Description:Studying the nodal quasiparticles in superconducting cuprates by
photoemission with highly improved momentum resolution, we show that a
new "kink" feature in the scattering rate is a key to uncover the
nature of electron correlations in these compounds. Our data provide
evidence that the main doping independent contribution to the
scattering can be well understood in terms of the conventional Fermi
liquid model, while the additional doping dependent contribution has a
magnetic origin. This sheds doubt on applicability of a phonon-mediated
pairing mechanism to high-temperature superconductors.
