Anomaly constraint on massless QCD and the role of Skyrmions in chiral symmetry breaking

Journal of High Energy Physics, 2018
We discuss consequences of the ’t Hooft anomaly matching condition for Quantum Chromodynamics (QCD) with massless fundamental quarks. We derive the new discrete ’t Hooft anomaly of massless QCD for generic numbers of color N c and flavor N f , and an ...

Gravitational F-terms of N=1 Supersymmetric SU(N) Gauge Theories

, 2003
We use the generalized Konishi anomaly equations and R-symmetry anomaly to compute the exact perturbative and non-perturbative gravitational F-terms of four-dimensional N=1 supersymmetric gauge theories. We formulate the general procedure for computation

Chiral fermions, dimensional regularization, and the trace anomaly

Nuclear Physics B, 2022
We investigate the trace anomaly of a chiral fermion in dimensional regularization, considering in detail the simplest case of coupling to an abelian gauge field. We apply the Breitenlohner-Maison/'t Hooft-Veltman prescription for dealing with the chiral

’t Hooft anomaly matching condition and chiral symmetry breaking without bilinear condensate

Journal of High Energy Physics, 2019
We explore 4-dimensional SU(N) gauge theory with a Weyl fermion in an irreducible self-conjugate representation. This theory, in general, has a discrete chiral symmetry.

Pseudo chiral anomaly in zigzag graphene ribbons [PDF]

J. Phys.: Condens. Matter 32 025301 (2020), 2019
As the three-dimensional analogs of graphene, Weyl semimetals display signatures of chiral anomaly which arises from charge pumping between the lowest chiral Landau levels of the Weyl nodes in the presence of parallel electric and magnetic fields. In this work, we study the pseudo chiral anomaly and its transport signatures in graphene ribbon with ...

Bulk Versus Edge in the Quantum Hall Effect

, 1996
The manifestation of the bulk quantum Hall effect on edge is the chiral anomaly. The chiral anomaly {\it is} the underlying principle of the ``edge approach'' of quantum Hall effect. In that approach, $\sxy$ should not be taken as the conductance derived

Anomalies from Immersions [PDF]

arXiv, 2001
Two forms of anomalies for chiral spinors living on submanifolds of the spacetime are obtained from the integrality theorem for immersions. The first form of the chiral anomaly is the usual for chiral spinors living on D-brane and O-plane intersections, the second form is exotic.
