Massive vector field perturbations in the Schwarzschild spacetime from supersymmetric gauge theory

Abstract: The master equation of the Proca field in the Schwarzschild spacetime is studied by using the Seiberg-Witten/quasinormal modes duality. We establish the dictionary between the parameters in gauge and gravity theories, since both sides lead to Heun-type equations. Applying the technique of instanton counting, we analytically find the eigenfrequencies of the quasinormal modes and quasi-bound states for massive vector fields around black holes, with the boundary conditions linked by the connection formula. The results show consistency with known numerical researches in the literature.
