Description

We present preliminary result of the electromagnetic form factor of the pion at $m_\pi=0.145$ GeV on the large volume corresponding to $L = 8.1$ fm using stout-smearing Wilson clover quark action and Iwasaki gauge action at $a^{-1}=2.333$ GeV. The mean square charge radius is estimated from the results at small space-like momentum transfer with the NLO formula in SU(2) chiral perturbation theory. Our preliminary result of the charge radius is compared with the experiment and previous lattice calculations.
