The Edinburgh Plot is a scale independent way of presenting lattice QCD calculations over a wide range of quark masses. In this sense it is appealing as an indicator of how the approach to physical quark masses is progressing. The difficulty remains that even the most state of the art calculations are still at quark masses that are too heavy to apply dimensionally-regulated chiral perturbation ...

Observing Chiral Nonanalytic Behavior with FLIC Fermions

First results from lattice QCD revealing the chiral nonanalytic behavior of nucleon and ∆ baryon magnetic moments are presented. Numerical simulations in the light quark mass regime employing the nonperturbatively O(a)-improved conserved vector current are enabled via FLIC fermions. Quenched chiral perturbation theory for the nucleon and ∆ magnetic moments is derived to next to next to leading ...

Nonanalytic Inference

The present study examined the effect of typicality and category association in inferences about category members. Results from three experiments indicated that the two measures had opposing effects, such that participants preferred to make inferences from more typical to less typical category exemplars, but were more reluctant to make inferences from more to less associated members of the cate...
