Query: Greybody factors for a black hole in massive gravity   An exact solution was recently found in the massive gravity theory having the
form of Schwarzschild-dS black holes with some additional background fields.
Hawking radiation will occur at the event and cosmological horizons having the
blackbody spectrum, which will be modified by the geometry outside the black
hole. In this paper, we study the greybody factors of a test scalar,
considering its minimal coupling with the background geometry. The case of
small black holes with the horizon radius much smaller than the cosmological dS
radius is studied numerically. The case of near-extremal black holes with the
horizon radius comparable to the cosmological dS radius is studied
analytically. In addition, we considered the coupling of the test field with
the background {St\"uckelberg} fields, which in turn leads to reductions in
particle emission and some non-trivial features (resonances) in the greybody
factors.
