DESCRIPTION:Title: <a href="https://researchseminars.org/talk/QTFMS/30/">N
 on-supersymmetric Branes and Discrete Topological Terms</a>\nby Ivano Basi
 le (Max Planck Institute for Physics) as part of Quantum Theories of Field
 s\, Matter\, and Strings\n\n\nAbstract\nIn a recent work\, Tachikawa and Z
 hang proved the existence of a discrete topological term in the unique non
 -supersymmetric heterotic string with no tachyons in ten dimensions. This 
 theory features NS5-branes\, whose chiral degrees of freedom are not well-
 understood due to the absence of dualities or supersymmetry. In this paper
 \, we test the consistency of a tentative spectrum obtained by anomaly inf
 low\, studying the relation between the worldvolume theory and the discret
 e topological term in spacetime. Furthermore\, we conduct a bottom-up inve
 stigation of lower-dimensional gravitational theories with the same method
