  We consider the stability of six-dimensional singly rotating Myers-Perry
black holes under massive scalar perturbations. Using Leaver's continued
fraction method, we compute the quasinormal modes of the massive scalar fields.
All modes found are damped under the quasinormal boundary conditions. It is
also found that long-living modes called quasiresonances exist for large scalar
masses as in the four-dimensional Kerr black hole case. Our numerical results
provide a direct and complement evidence for the stability of six-dimensional
MP black holes under massive scalar perturbation.
