Gauge anomaly cancellation in chiral gauge theories
Gabriel Di Lemos Santiago Lima, Rafael Chaves Souto Araujo, Sebastiao Alves Dias
We consider chiral fermions interacting minimally with abelian and non-abelian gauge fields. Using a path integral approach and exploring the consequences of a mechanism of symmetr…
Edge modes in the fractional quantum Hall effect without extra edge fermions
Gabriel Di Lemos Santiago Lima, Sebastiao Alves Dias
We show that the Chern-Simons-Landau-Ginsburg theory that describes the quantum Hall effect on a bounded sample is anomaly free and thus does not require the addition of extra chir…
Exact Renormalization of Massless QED2
Rodolfo Casana, Sebastiao Alves Dias
We perform the exact renormalization of two-dimensional massless gauge theories. Using these exact results we discuss the cluster property and confinement in both the anomalous and…
On the origin of divergences in massless
Rodolfo Casana, Sebastiao Alves Dias
We show that ultraviolet divergences found in fermionic Green's functions of massless have an essentially non-perturbative nature. We investigate their origin both in gauge…
On the Renormalizability of Theories with Gauge Anomalies
Rodolfo Casana, Sebastiao Alves Dias
We consider the detailed renormalization of two (1+1)-dimensional gauge theories which are quantized without preserving gauge invariance: the chiral and the "anomalous" Schwinger m…
On Bosonization Ambiguities of Two Dimensional Quantum Electrodynamics
S. A. Dias, M. B. Silva Neto
We study bosonization ambiguities in two dimensional quantum electrodynamics in the presence and in the absence of topologically charged gauge fields. The computation of fermionic…
