Query: Bose-Einstein Interference and Factorization at High Energies   We consider the emission or absorption of $n$ identical bosons from an
energetic or a massive particle, in which the bosons and the source particle
are allowed to be offshell. The Bose-Einstein symmetrized amplitude can be
decomposed into sums and products of more elementary objects which we choose to
call `atoms'. The origin of this decomposition, its significance and some of
its applications will be summarized.
