Zero-level integrable modules over twisted affine Lie superalgebras

The main result of this paper is the characterization of zero-level integrable finite weight modules, over twisted affine Lie superalgebras. We prove that such a module is parabolically induced from a module which is obtained, in a prescribed way, from a module over a Lie algebra $\mathcal{L}$ which is either a $\text{bbbz}$-graded abelian Lie algebra or a direct sum of a $\text{bbbz}$-graded abelian Lie algebra and the so-called quadratic Lie superalgebra $\mathcal{Q}$. We give also a complete characterization of both finite dimensional simple $\mathcal{Q}$-modules as well as bounded finite weight $\text{bbbz}$-graded simple $\mathcal{Q}$-modules.
