✦ Synopsis

We report our recent study of the K. meson by full-QCD simulation with Wilson fermions on the 83 x 16 lattice at p = 4.8. Contrary to our o meson calculation, where the disconnected diagram results in very light mass, we obtain a rather heavy kappa particle, i.e., mn/rnK* N 2. This preliminary result does not agree with recent experimental values.

We re-analyse meson sector data from the CP-PACS collaboration's dynamical simulations [I]. Our analysis uses several different approaches, and compares the standard naive linear fit with the Adelaide Anzatz. We find that setting the scale using the J parameter gives remarkable agreement among data
