Abstract
Emission of hard microscopic string (graviton) by an excited macroscopic string may be viewed as a model of branching of a -dimensional baby universe off large parent one. We show that, apart from a trivial factor, the total emission rate is not suppressed by the size of the macroscopic string. This implies unsuppressed loss of quantum coherence in -dimensional parent universe.
