  Recently, a static spherically symmetric black hole solution was found in
gravity nonminimally coupled a background Kalb-Ramond field. The Lorentz
symmetry is spontaneously broken when the Kalb-Ramond field has a nonvanishing
vacuum expectation value. In this work, we focus on the quasinormal modes and
greybody factor of this black hole. The master equations for the perturbed
scalar field, electromagnetic field, and gravitational field can be written
into a uniform form. We use three methods to solve the quasinormal frequencies
in the frequency domain. The results agree well with each other. The time
evolution of a Gaussian wave packet is studied. The quasinormal frequencies
fitted from the time evolution data agree well with that of frequency domain.
The greybody factor is calculated by Wentzel-Kramers-Brillouin (WKB) method.
The effect of the Lorentz-violating parameter on the quasinormal modes and
greybody factor are also studied.
