Large-N Solution of the Heterotic CP(N-1) Model with Twisted Masses
**

Two-dimensional CP(N-1) models
emerged as effective low-energy theories on
the worldsheet of non-Abelian strings in a class of
four-dimensional N=2 supersymmetric gauge theories.
Here we focus on a particular model, so called
heterotic N=(0,2) supersymmetric CP(N-1) model with twisted masses.
We solve this model in the large-N approximation. Dynamical scenarios at
large and small masses are studied.
We found three distinct phases and two lines of phase transitions.
