Type I anomaly cancellation revisited
Saghar S. Hosseini, Yuji Tachikawa, Hao Y. Zhang
We revisit the issue of how the perturbative and global fermion anomaly of Type I string theory in ten dimensions is cancelled by the Green-Schwarz mechanism using the RR fields. T…

On a -valued discrete topological term in 10d heterotic string theories
Yuji Tachikawa, Hao Y. Zhang
We show that the low-energy effective actions of two ten-dimensional supersymmetric heterotic strings are different by a -valued discrete topological term even after…

On a class of selection rules without group actions in field theory and string theory
Justin Kaidi, Yuji Tachikawa, Hao Y. Zhang
We discuss a class of selection rules which i) do not come from group actions on fields, ii) are exact at tree level in perturbation theory, iii) are increasingly violated as the l…
