  We derive the twisted-mass potential in N=(2,2) CP(N-1) theory on the world
sheet of the non-Abelian string from the bulk N=2 theory with massive (s)quarks
by determining the profile functions of the adjoint fields. Although this
potential was indirectly found some time ago, this is the first direct
derivation from the bulk.
  As an application of the adjoint field profiles, we compute and confirm the $
| \mu \sigma | $ potential (where $ \sigma $ is a scalar field in the gauge
supermultiplet) which arises in the effective two-dimensional theory on the
string due to the supersymmetry breaking bulk mass term $ \mu A^2 $ for the
adjoint matter.
