Update on the physics of light pseudoscalar mesons

)chiral lagrangian. We have new data for lattice spacing a ≈0.15 fm withseveral values of the light quark mass down to one-tenth the strange quark mass, higher statisticsfor a ≈ 0.09 fm with the light quark mass equal to one-tenth the strangequark mass, and initialresults for our smallest lattice spacing, a ≈0.06 fm with light quark mass two-fifths of the strangequark mass.XXIVth International Symposium on Lattice Field TheoryJuly 23-28, 2006Tucson, Arizona, USA
