On a $Z_3$ Topological Term in 10d Heterotic String Theories
Abstract: I will compare the gravitational sectors of two 10d heterotic string theories, with E8 x E8 and Spin(32)/$Z_2$ gauge groups, and show that they differ by a subtle $Z_3$-valued topological term. I also discuss its relation to the mathematics of topological modular forms. This is based on my collaboration https://arxiv.org/abs/2403.08861 with Hao Zhang.
