摘要：I summarize the physics results obtained from large-scale dynamical overlap fermion simulations
by the JLQCD and TWQCD collaborations. The numerical simulations are performed at a fixed
global topological sector; the physics results in the q -vacuumis reconstructed by correcting the finite
volume effect, for which the measurement of the topological susceptibility is crucial. Physics
applications we studied so far include a calculation of chiral condensate, pion mass, decay constant,
form factors, as well as (vector and axial-vector) vacuumpolarization functions and nucleon
sigma term.
