The sigma model on complex projective superspaces
The sigma model on complex projective superspaces
The sigma model on projective superspaces $ \mathbb{C}{\mathbb{P}^{S - 1\left| S \right.}} $ gives rise to a continuous family of interacting 2D conformal field theories which are parametrized by the curvature radius R and the theta angle θ. Our main goal is to determine the spectrum of the model, non-perturbatively …
