Gauge Anomalies in an Effective Field Theory, the On-Shell Way

• Ofri Telem (Berkeley)

In a seminal paper, John Preskill showed how gauge theories in the Higgs phase can couple consistently to anomalous matter content. This formulation is complementary to the traditional approach in which gauge theories with an anomalous fermion content necessitate gauged-WZW terms that cancel the fermion anomaly. The gauge invariant statement that follows is that anomalous theories in the Higgs phase are completely consistent with unitarity, when considered as EFTs. In this work we shed more light on the consistency of anomalous gauge theories in the Higgs phase, using the recently discovered, on-shell notion of gauge anomalies as tension between locality and unitarity at 1-loop. We demonstrate how this tension is reconciled in the Higgs phase by calculating the 1-loop contribution of massless chiral fermions to the massive 4-vector amplitude. This is the one of the first full 1-loop calculations that combine the method of generalized unitarity with Nima Arkani-Hamed’s massive amplitude formalism.

Aspects of Nonlinear Effect on Black Hole Superradiance

• Hajime Fukuda (Berkeley)

Under some conditions, light boson fields grow exponentially around a rotating black hole, called the superradiance instability. We discuss effects of nonlinear interactions of the boson on the instability. In particular, we focus on the effect of the particle production and show that the growth of the boson cloud may be saturated much before the black hole spin is extracted by the boson cloud, while the nonlinear interactions also induce the boson emission. For application, we revisit the superradiant instability of the standard model photon, axion and hidden photon.
