Localizing non-linear $\mathcal{N}=(2,2)$ sigma model on $S^2$

Victor Alekseev, Guido Festuccia, Victor Mishnyakov +2

We present a systematic study of $\mathcal{N}=(2,2)$ supersymmetric non-linear sigma models on $S^2$ with the target being a Kähler manifold. We discuss their reformulation in terms o…
