The late-time tail behaviour of massive scalar fields is studied analytically in a stationary axisymmetric Einstein–Maxwell Dilaton–Axion (EMDA) black hole geometry. It is shown that the asymptotic behaviour of massive perturbations is dominated by the oscillatory inverse power-law decaying tail t −( l +3/2) sin (μ t ) at the intermediate late times, and by the asymptotic tail t −5/6 sin (μ t ) at asymptotically late times, with μ being field mass. Our result seems to suggest that the intermediate tails t −( l +3/2) sin (μ t ) and the asymptotically tails t −5/6 sin (μ t ) may be a quite general feature for evolution of massive scalar fields in any four-dimensional asymptotically flat rotating black hole backgrounds.
