A Gravity Dual of the Chiral Anomaly [PDF]

open access: yes, 2002
We study effects associated with the chiral anomaly for a cascading $SU(N+M)\times SU(N)$ gauge theory using gauge/gravity duality. In the gravity dual the anomaly is a classical feature of the supergravity solution, and the breaking of the U(1) R ...

Widening the U(1)Lμ−Lτ Z′ mass range for resolving the muon g − 2 anomaly

open access: yesPhysics Letters B, 2022
Exchanging a Z′ gauge boson is a favored mechanism to solve the muon (g−2)μ anomaly. Among such models the Z′ from U(1)Lμ−Lτ gauge group has been extensively studied.

Mixed gauge and gravitational chiral anomalies

open access: yesPhysics Letters B, 1985
Abstract We consider critically some recent results on the breaking of global and local Lorentz invariance by a chiral fermion coupled to a gauge field, and we obtain a new formulation of mixed gauge gravitational anomalies that shows in particular an equivalence among Lorentz, Einstein and gauge anomalies.

Anomaly Cancellations in the Type I D9-anti-D9 System and the USp(32) String Theory

open access: yes, 1999
We check some consistency conditions for the D9-anti-D9 system in type I string theory. The gravitational anomaly and gauge anomaly for SO(n) x SO(m) gauge symmetry are shown to be cancelled when n-m=32. In addition, we find that a string theory with USp(

Chiral gauged fermions on a lattice [PDF]

open access: yes, 2000
The chiral fermion model with local multifermion interactions proposed in Nucl. Phys. B486 (1997) 282 and Phys. Rev. D61 (2000) 054502 processes an exact SU_L(2) chiral gauge symmetry and SU_L(2) by U_R(1) chiral flavour symmetry on a lattice and a ...

Structural biology of ferritin nanocages

open access: yesFEBS Letters, EarlyView.
Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

Weyl conformal geometry vs Weyl anomaly

open access: yesJournal of High Energy Physics, 2023
Weyl conformal geometry is a gauge theory of scale invariance that naturally brings together the Standard Model (SM) and Einstein gravity. The SM embedding in this geometry is possible without new degrees of freedom beyond SM and Weyl geometry, while ...

Diffusion Spectrum Imaging Maps Early Axonal Loss and a Unique Progressive Signal in Neuronal Intranuclear Inclusion Disease

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To delineate specific in vivo white matter pathology in neuronal intranuclear inclusion disease (NIID) using diffusion spectrum imaging (DSI) and define its clinical relevance. Methods DSI was performed on 42 NIID patients and 38 matched controls.

Discrete gauge anomalies and instantons

open access: yesJournal of High Energy Physics
Abstract We revisit anomalous phases related to large gauge transformations, such as the Witten anomaly. The latter, known to plague d = 4 Sp(k) theories, is well-understood in terms of π 4(Sp(k)) = ℤ2, but it also has an oblique relation to the instantons, labeled by π 3(G) = ℤ, via the fermion zero mode ...

Planar and Nonplanar Konishi Anomalies and Effective Superpotential for Noncommutative N=1 Supersymmetric U(1)

open access: yes, 2005
The Konishi anomalies for noncommutative N=1 supersymmetric U(1) gauge theory arising from planar and nonplanar diagrams are calculated. Whereas planar Konishi anomaly is the expected \star-deformation of the commutative anomaly, nonplanar anomaly ...
