Abstract
Emission of hard microscopic string (graviton) by an excited macroscop ic string may be viewed as a model of branching of a (1+1)-dimensional baby universe off large parent one. We show that, apart from a trivia l factor, the total emission rate is not suppressed by the size of the macroscopic string. This implies unsuppressed loss of quantum coheren ce in (1+1)-dimensional parent universe.
