| dc.description.abstract | Starting from a recent model where the (K) over barN amplitudes are evaluated from the chiral Lagrangians using a coupled-channel unitary method, we evaluate here the scattering length for K--deuteron scattering. We find that the double scattering contribution is very large compared to the impulse approximation and that the charge-exchange contribution of this rescattering is as large as the sequential K scattering on the two nucleons. Higher-order rescattering corrections are evaluated using coupled channels with K- and (K) over bar (0) within the integral form of the fixed centre approximation to the Faddeev equations. The higher-order corrections involving intermediate pions and hyperons are found negligible. (C) 2001 Elsevier Science B.V. All rights reserved. | |
