quasiparticle dispersion has a kink along the diagonal Brillouin zone at the energy of the order 50 meV, for realistic values of the … parameters. The energy and momentum distribution curves (EDC, MDC) along the diagonal are also analyzed. The results for the EDC … derived quasiparticle width reveals an anomalous drop in the low-energy scattering rate at the same energy of the kink. This …
