Query: Large-N Solution of the Heterotic N=(0,2) Two-Dimensional CP(N-1) Model   We continue explorations of non-Abelian strings, focusing on the solution of
a heterotic deformation of the CP(N-1) model with an extra right-handed fermion
field and N=(0,2) supersymmetry. This model emerges as a low-energy theory on
the worldsheet of the BPS-saturated flux tubes (strings) in N=2 supersymmetric
QCD deformed by a superpotential of a special type breaking N=2 supersymmetry
down to N=1. Using large-N expansion we solve this model to the leading order
in 1/N. Our solution exhibits spontaneous supersymmetry breaking for all values
of the deformation parameter. We identify the Goldstino field. The discrete
Z_{2N} symmetry is shown to be spontaneously broken down to Z_2; therefore, the
worldsheet model has N strictly degenerate vacua (with nonvanishing vacuum
energy). Thus, the heterotic CP(N-1) model is in the deconfinement phase. We
can compare this dynamical pattern, on the one hand, with the N=(2,2) CP(N-1)
model which has N degenerate vacua with unbroken supersymmetry, and, on the
other hand, with nonsupersymmetric CP(N-1) model with split quasivacua and the
Coulomb/confining phase. We determine the mass spectrum of the heterotic
CP(N-1) model in the large-N limit.
