  • Plots

These plots are modified versions of those found in "Toward the excited ..." suitable for use in talks. These results are all from dynamical studies with light and strange quarks - that is they are "unquenched" to use a wholly negative terminology.

    • Exotic J^{{PC}} meson masses as a function of pion mass. The light pink circles are 1^{{-+}} quenched estimates from the references above, the darker pink circles are 1^{{-+}} dynamical estimates from the references above. The triangles are the new results on lattices of spatial volume \sim 2^{3} and \sim 2.5^{3} - the red points are 1^{{-+}}, blue points 0^{{+-}} and green 2^{{+-}}. Other exotic quantum numbers, like 0^{{--}}, 3^{{-+}} are somewhat heavier.
