โœฆ Synopsis


Motivated

by recent measurements at J-Lab, the pion electromagnetic form-factor is investigated with quenched domain wall fermions and a renorma,lization group improved gauge action called DBW2. We see that quark mass dependence of the form-factor with finite momentum transfers is rather small.
