Abstract
We illustrate a technique for fitting lattice QCD correlators to sums of exponentials that is significantly faster than traditional fitting methods—10–40 times faster for the realistic examples we present. Our examples are drawn from a recent analysis of the Υ spectrum, and another recent analysis of the D→π semileptonic form factor. For single correlators, we show how to simplify traditional effective-mass analyses.
