Radiative transition decay width for has been calculated on twisted mass gauge configurations. In this simulation, twisted boundary conditions are applied to compute corresponding correlation functions. It helps us obtain form factors with more low four transfer momentum that benefit fitting the decay width more accurately. The calculated decay width for is smaller than the experiment data in particle data group (PDG).
