Anomaly cancellation in effective field theories from the covariant derivative expansion

Timothy Cohen

We extend our recently proposed formalism for calculating anomalies of global and gauge symmetries using the covariant derivative expansion to include a general class of operators that can appear in relativistic effective field theories (EFTs). This allows ...

Large deviations in the early Universe

Timothy Cohen

Fluctuations play a critical role in cosmology. They are relevant across a range of phenomena from the dynamics of inflation to the formation of structure. In many cases, these fluctuations are coarse grained and follow a Gaussian distribution as a consequ ...
