A twist at infinite distance in the CHL string

We analyze a space-time algebra of BPS states that emerges in the infinite distance limit in the moduli space of the nine-dimensional CHL string as the theory decompactifies to the ten-dimensional \(\text{E}_8 \times \text{E}_8\) heterotic string. We find an affine algebra as expected from the heter...

Description
Summary:We analyze a space-time algebra of BPS states that emerges in the infinite distance limit in the moduli space of the nine-dimensional CHL string as the theory decompactifies to the ten-dimensional \(\text{E}_8 \times \text{E}_8\) heterotic string. We find an affine algebra as expected from the heterotic case, but in a twisted version.
