On the Weyl anomaly for chiral fermions
Enrique Alvarez, Luis Alvarez-Gaume, Jesus Anero +1
We compute the parity-odd part of the Weyl anomaly for chiral fermions in a background gravitational field. We start from a manifestly real form of the Lagrangian (that is, not onl…
Lectures on Field Theory and the Standard Model: A Symmetry-Oriented Approach
Luis Alvarez-Gaume, Miguel A. Vazquez-Mozo
The standard model of particle physics represents the cornerstone of our understanding of the microscopic world. In these lectures we review its contents and structure, with a part…
Anomalies and the Green-Schwarz Mechanism
Luis Alvarez-Gaume, Miguel A. Vazquez-Mozo
Anomalies are a very powerful tool in constraining theories beyond the standard model. We give a pedagogical overview of some topics illustrating the important role played by space…
Selected Topics in the Large Quantum Number Expansion
Luis Álvarez Gaumé, Domenico Orlando, Susanne Reffert
In this review we study quantum field theories and conformal field theories with global symmetries in the limit of large charge for some of the generators of the symmetry group. At…
Large charge at large N
Luis Alvarez-Gaume, Domenico Orlando, Susanne Reffert
We apply the large-charge expansion to O(N) vector models starting from first principles, focusing on the Wilson-Fisher point in three dimensions. We compute conformal dimensions a…
Compensating strong coupling with large charge
Luis Alvarez-Gaume, Orestis Loukas, Domenico Orlando +1
We study some (conformal) field theories with global symmetries in the sector where the value of the global charge is large. We find (as expected) that the low energy excitatio…
