Criticism of the accelerated-convergence-expansion partial-wave analysis of K+p elastic scattering

The accelerated-convergence-expansion (ACE) method of phase-shift analysis has been applied recently to K⁺p elastic scattering. Its conformal-mapping technique generates larger high partial waves (HPW) than previous analyses. We calculate the HPW's from π-exchange, and estimate all possible uncertainties. The results are much smaller than and in clear contradiction with the ACE predictions for the HPW's. We suggest modifications of the latter to remedy this sad state of affairs.
