我们考虑的演化过程中形成的原始黑洞的高能阶段的膜世界的情况。我们表明，从周围的辐射浴吸积的效果是占主导地位的蒸发相比，这样的黑洞。这种特征一直持续到物质（或黑洞）开始支配总能量密度，这可能发生在高能阶段或更晚。我们发现，黑洞的蒸发时间可能是显着的大，即使是小初始质量的黑洞生存，直到几个宇宙学有趣的时代。
We consider the evolution of primordial black holes formed during the high energy phase of the braneworld scenario. We show that the effect of accretion from the surrounding radiation bath is dominant compared to evaporation for such black holes. This feature lasts till the onset of matter (or black hole) domination of the total energy density which could occur either in the high energy phase or later. We find that the black hole evaporation times could be significantly large even for black holes with small initial mass to survive until several cosmologically interesting eras.
