 abstract = {We find that localized quantum N-body soliton states exist for a
derivative nonlinear Schrodinger (DNLS) model within an extended range
of coupling constant (xiq) given by 0 <
\xiq\ < \ 1/h tan(pi/N-1).
We also observe that soliton states with both positive and negative
momentum can appear for a fixed value of xiq. Thus the chirality
property of classical DNLS solitons is not preserved at the quantum
level. Furthermore, it is found that the solitons with positive
(negative) chirality have positive (negative) binding energy. (C) 2004
