EVAPORATION OF SCHWARZSCHILD BLACK-HOLES IN MATRIX-THEORY

Recently, in collaboration with Susskind, we proposed a model of Schwa rzschild black holes in Matrix Theory. A large Schwarzschild black hol e is described by a metastable bound state of a large number of D0-bra nes which are held together by a background, whose structure has so fa r been understood only in 8 and Il dimensions. The Hawking radiation p roceeds by emission of small clusters of D0-branes. We estimate the Ha wking rate in the Matrix Theory model of Schwarzschild black holes and find agreement with the semiclassical rate up to an undetermined nume rical coefficient of order 1.
