## Recent angle resolved photoemission experiments by Kanigel et al., [Nature Physics 2 (2006) 447] show that the low energy electronic excitations in the normal state of underdoped cuprate superconductors exist on open Fermi arcs which shrink upon cooling, and appear to extrapolate to nodal poin

โฆ Synopsis
The mechanism for the evolution of the Fermi arc with increasing the temperature in high-T c cuprates has been proposed. We have discussed the electrical resistivity in the normal state and the linear-like decreasing of the spin part of the Knight shift from the large pseudogap, whose corresponding temperature is T mK , to the small pseudogap, whose corresponding temperature is T * .

The quasiparticles around the Fermi level of the so-called d-p model are shown to behave as the mid-gap stat~ on the basis of the formal theory of Fermi liquid together with the Gutzwiller-type approximation for estimation of the chemical potential. On its basis, it is shown that the wavenumber-depe
