Angle-resolved photoemission spectroscopy (ARPES) is used to study thespectral function of the optimally doped high-T$_c$ superconductor(Bi,Pb)$_2$Sr$_2$CaCu$_2$O$_{8+\delta}$ in the vicinity of the antinodal pointin the superconducting state. Using a parameterized self-energy function, itwas possible to describe both the coherent and the incoherent spectral weightof the bonding and the antibonding band. The renormalization effects can beassigned to a very strong coupling to the magnetic resonance mode and at higherenergies to a bandwidth renormalization by a factor of two, probably caused bya coupling to a continuum. The present reevaluation of the ARPES data allows tocome to a more reliable determination of the value of the coupling strength ofthe charge carriers to the mode. The experimental results for the dressing ofthe charge carriers are compared to theoretical models.Comment: 12 pages, 7 figure
