| contents | Kerr Sen black holes possess stretchon parameters and hidden conformal symmetries. The superradiant stability and steady state resonance of such black holes warrant further investigation and form the primary motivation for this study. In this work,we introduce an additional variable, referred to as y, to generalize the findings of the previous study. When the frequency of the perturbation lies within a specific range namely, above a certain threshold determined by the spin parameter and below the sum of the azimuthal quantum number times the angular velocity at the horizon and the product of the charge with the electric potential at the horizon,the Kerr Sen black hole exhibits superradiant stability. This behavior is similar to the superradiant characteristics previously observed in KN black holes. |
