摘      要：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(mut) at the intermediate late times, and by the asymptotic tail t(-5/6) sin(mut) at asymptotically late times, with mu being held mass. Our result seems to suggest that the intermediate tails t(-(l+3/2)) sin(mut) and the asymptotically tails t(-5/6) sin(mut) may be a quite general feature for evolution of massive scalar fields in any four-dimensional asymptotically flat rotating black hole backgrounds.
