Nonminimally coupled massive scalar field in a 2D black hole: Exactly solvable model - art. no. 125026

We study a nonminimal massive scalar field in the background of a two-dimen sional black hole spacetime. We consider the black hole which is the soluti on of the 2D dilaton gravity derived from string-theoretical models. We fin d an explicit solution in a closed form for all modes and the Green functio n of the scalar field with an arbitrary mass and a nonminimal coupling to t he curvature. Greybody factors, the Hawking radiation, and (phi (2))(ren) a re calculated explicitly for this exactly solvable model.
