Omega vs. pi, and 6d anomaly cancellation
Joe Davighi, Nakarin Lohitsiri
In this note we review the role of homotopy groups in determining non-perturbative (henceforth `global') gauge anomalies, in light of recent progress understanding global anomalies…
The algebra of anomaly interplay
Joe Davighi, Nakarin Lohitsiri
We give a general description of the interplay that can occur between local and global anomalies, in terms of (co)bordism. Mathematically, such an interplay is encoded in the non-c…
Differential cohomology and topological actions in physics
Joe Davighi, Ben Gripaios, Oscar Randal-Williams
We use differential cohomology to systematically construct a large class of topological actions in physics, including Chern-Simons terms, Wess-Zumino-Novikov-Witten terms, and thet…
Undulating Dark Matter
Joe Davighi, Matthew McCullough, Joseph Tooby-Smith
We suggest that an interplay between microscopic and macroscopic physics can give rise to dark matter (DM) whose interactions with the visible sector fundamentally undulate in time…
Anomalies and accidental symmetries: charging the scalar leptoquark under -
Joe Davighi, Matthew Kirk, Marco Nardecchia
While the scalar leptoquark presents a possible tree-level explanation of the flavour anomalies, it suffers from two conceptual problems which are often d…
Anomaly interplay in gauge theories
Joe Davighi, Nakarin Lohitsiri
We discuss anomaly cancellation in gauge theories in four dimensions. For a gauge theory defined with a spin structure, the vanishing of the bordism group $Ω_5^{\text…
