摘要：

We investigate the electromagnetic form factor of D-s* meson using N-f = 2 twisted mass lattice quantum chromodynamics gauge configurations. The numerical simulations are carried out under twisted boundary conditions which are helpful to increase the resolution in momentum space. We determine electromagnetic form factors with more small four-momentum transfer, and further fit the charge radius for D-s* meson.
