Аннотация: 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 Sr2CuO2Cl2 In (0,0)-(pi,pi) and (0,pi)-(pi,0) directions our calculations show a better agreement vs t-J model (in (0,0)-(pi,0) directions), where tПоказать полностьюhe largest discrepancy of t-J and ARPES results takes place, we get a much smaller dispersion. The new ARPES data on Sr2CuO2Cl2 are in good agreement with our calculation in the (0,0)-(pi,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.
