Radiative transition decay width for was calculated by using twisted mass lattice quantum chromodynamics gauge configurations in this preliminary study. The simulation has been performed on lattices with lattice spacings and lattice size (Ens.C1), and and lattice size (Ens.B1) respectively. In this simulation, we have considered the parity mixing effect by using variational method. The calculated central value for the decay width is closer to the experimental data than that in previous lattice studies.
