Abstract
The dispersion of a hole in the antiferromagnetic background is calculated in the framework of the 6-band, p-d model and compared with results of the, t-J model and ARPES measurements on, Sr 2 , CuO 2 , C1 2 . In, (0,, 0)-(π,π)and, (0,, π)-(π,0)directions our calculations show a better agreement vs, t-J model (in, (0,, 0)-(π,0)directions), where the largest discrepancy of, t-J and ARPES results takes place, we get a much smaller dispersion. The new ARPES data on, Sr 2 , CuO 2 , C1 2 are in good agreement with our calculation in the, (0,, 0)-(π,0)direction. The implication for the pairing mechanism and the nature of the local boson (spin exciton) resulted from the multiband strongly correlated electron structure analysis are discussed.
