It is generally believed that behaviours of quasiparticles (holes) in
high-TCβ cupurates should be attributed to the two-dimensional (2D)
electronic states in the CuO2β planes. The various anomalies of the
transport coefficients for temperatures above TCβ are long-standing
insoluble puzzles and cause serious controversy. Here we reanalyse the
published experimental date of LSCO cupurates. We find that the normal-state
susceptibility, resistivity, Hall coefficient etc vary precisely as T2lnT as a function of temperature T in agreement with the prediction of the
Fermi liquid model. The quasiparticles are shown to definitely behave as a 3D
Fermi liquid. Various attempts to describe the system in terms of non-Fermi
liquids,e.g. the RVB state, seem to be erroneous.Comment: 2 pages, 3 Postscript figures, To appear in Physica
