Natural inflation, strong dynamics, and the role of generalized anomalies (2020)
Journal Article
Anber, M. M., & Baker, S. (2020). Natural inflation, strong dynamics, and the role of generalized anomalies. Physical Review D, 102(10), Article 103515. https://doi.org/10.1103/physrevd.102.103515

We revisit models of natural inflation and show that the single-field effective theory described by the potential V ( a ) ∼ cos a f breaks down as the inflaton a makes large-field excursions, even for values of f smaller than the Planck scale. To rem... Read More about Natural inflation, strong dynamics, and the role of generalized anomalies.

Generalized ’t Hooft anomalies on non-spin manifolds (2020)
Journal Article
Anber, M. M., & Poppitz, E. (2020). Generalized ’t Hooft anomalies on non-spin manifolds. Journal of High Energy Physics, 2020(4), Article 97. https://doi.org/10.1007/jhep04%282020%29097

We study the mixed anomaly between the discrete chiral symmetry and general baryon-color-flavor (BCF) backgrounds in SU(Nc) gauge theories with Nf flavors of Dirac fermions in representations ℛc of N -ality nc, formulated on non-spin manifolds. We sh... Read More about Generalized ’t Hooft anomalies on non-spin manifolds.

Deconfinement on axion domain walls (2020)
Journal Article
Anber, M. M., & Poppitz, E. (2020). Deconfinement on axion domain walls. Journal of High Energy Physics, 2020(3), Article 124. https://doi.org/10.1007/jhep03%282020%29124

We study SU(Nc) gauge theories with Dirac fermions in representations ℛ of nonzero N -ality, coupled to axions. These theories have an exact discrete chiral symmetry, which has a mixed ’t Hooft anomaly with general baryon-color-flavor backgrounds, ca... Read More about Deconfinement on axion domain walls.
