Abstract
Angle-resolved photoemission data on optimally doped and underdoped high-temperature superconductors reveal a dichotomy between the nodal and antinodal electronic excitations. We propose an explanation of this unusual phenomenon by employing the coupling between the quasiparticle and the commensurate and incommensurate magnetic excitations.
