Spin cobordism and the gauge group of type I/heterotic string theory by Christian Kneißl

“…In this work we compute the spin cobordism groups of the classifying space of Spin(32)/ℤ2 relevant to describing type I/heterotic string theory and explore their (shared) non-perturbative sector. …”

A heterotic Kähler gravity and the distance conjecture by Javier José Murgas Ibarra, Paul-Konstantin Oehlmann, Fabian Ruehle, Eirik Eik Svanes

“…We investigate properties of this new holomorphic theory, and in particular connections to the swampland distance conjecture in the context of heterotic string theory. In the process, we define a new type of symplectic cohomology theory, where the background complex structure Beltrami differential plays the role of the symplectic form.…”

Investigating 9d/8d non-supersymmetric branes and theories from supersymmetric heterotic strings by Yuta Hamada, Arata Ishige

“…Abstract We consider heterotic string theories in nine and eight dimensions. We identify the disconnected part of the spacetime gauge group by studying the outer automorphism of the charge lattices. …”
