Abstract

We present results on the D and $D_{s}$ meson electromagnetic form factors using $N_{f}=2$ twisted mass Lattice Quantum Chromodynamics (LQCD) gauge configurations. In this simulation, to access spatial components of momenta that are different from the integer multiples of $2\pi /L$ , we apply twisted boundary conditions to compute corresponding correlation functions. Electromagnetic form factors with more small four-momentum transfer are determined, and further we fit the electromagnetic charge radius for D and $D_{s}$ mesons, respectively.
