| 英文摘要 | In an exploratory study, using the tadpole improved clover Wilson quark action on small, coarse and anisotropic lattices, the pipi scattering length in the I = 2 channel is calculated within quenched approximation. A new method is proposed which enables us to make chiral extrapolation of our lattice results without calculating the decay constant on the lattice. Finite volume and finite lattice spacing errors are analyzed and the results are extrapolated towards the infinite volume and continuum limit. Comparisons of our lattice results with the new experiment and the results from Chiral Perturbation Theory are made. Good agreements are found. (C) 2002 Elsevier Science B.V. All rights reserved. |
