1302.6087 (Issaku Kanamori)

Lattice calculations of Ds to eta and eta' decay form factors    [PDF]

Issaku Kanamori
We report on lattice results of the form factors for semi-leptonic decays of the D_s meson to eta and eta', with n_f=2+1 configurations. The calculation contains disconnected fermion loop diagrams, which are challenging to calculate on the lattice. Our result shows that the disconnected diagrams give significant contributions to the form factors.
