Pion physics on the lattice

Understand

Recent results on pion physics from lattice QCD are reviewed.

• We discuss quark mass dependences of pion mass and decay constant and compare them with the predictions from chiral perturbation theory.
• In particular we focus on the convergence of chiral perturbation theory around strange quark mass region.
• We also consider quark mass as well as momentum dependences of pion form factors in recent full QCD simulations.
