We consider the implications of a phenomenological model self-energy for thecharge transport properties of the metallic phase of the overdoped cupratesuperconductors. The self-energy is the sum of two terms with characteristicdependencies on temperature, frequency, location on the Fermi surface, anddoping. The first term is isotropic over the Fermi surface, independent ofdoping, and has the frequency and temperature dependence characteristic of aFermi liquid. The second term is anisotropic over the Fermi surface (vanishingat the same points as the superconducting energy gap), strongly varies withdoping (scaling roughly with $T_c$, the superconducting transitiontemperature), and has the frequency and temperature dependence characteristicof a marginal Fermi liquid. Previously it has been shown this self-energy candescribe a range of experimental data including angle-dependentmagnetoresistance (ADMR) and quasi-particle renormalisations determined fromspecific heat, quantum oscillations, and angle-resolved photo-emissionspectroscopy (ARPES). Without introducing new parameters and neglecting vertexcorrections we show that this model self-energy can give a quantitativedescription of the temperature and doping dependence of a range of reportedtransport properties of Tl2201 samples. These include the intra-layerresistivity, the frequency dependent optical conductivity, the intra-layermagnetoresistance, and the Hall coefficient. The temperature dependence of thelatter two are particularly sensitive to the anisotropy of the scattering rateand to the shape of the Fermi surface. In contrast, the temperature dependenceof the Hall angle is dominated by the Fermi liquid contribution to theself-energy that determines the scattering rate in the nodal regions of theFermi surface.
