Associativity anomaly in string field theory [PDF]
We give a detailed study of the associativity anomaly in open string field theory from the viewpoint of the split string and Moyal formalisms. The origin of the anomaly is reduced to the properties of the special infinite size matrices which relate the conventional open string to the split string variables, and is intimately related to midpoint issues.

BRST-BFV analysis of anomalies in bosonic string theory interacting with background gravitational field [PDF]
The general BRST-BFV analysis of anomaly in the string theory coupled to background fields is carried out. An exact equation for c-valued symbol of anomaly operator is found and structure of its solutions is studied.

Anomaly Cancellations and String Symmetries in the Effective Field Theory [PDF]
This contribution briefly describes some developments of the use of string symmetries and anomaly cancellation mechanisms to include string loop corrections in the construction of the low-energy effective supergravity of superstrings. (Presented at the 27th International Conference on High Energy Physics, Glasgow, July 1994)

Trace and chiral anomalies in string and ordinary field theory from Feynman diagrams for non-linear sigma models [PDF]
We write general one-loop anomalies of string field theory as path integrals on a torus for the corresponding nonlinear sigma model. This extends the work of Alvarez-Gaum\'e and Witten from quantum mechanics to two dimensions. Higher world-volume loops contribute in general to nontopological anomalies and a formalism to compute these is developed.

Witten effect, anomaly inflow, and charge teleportation
We study a phenomenon that electric charges are “teleported” between two spatially separated objects without exchanging charged particles at all. For example, this phenomenon happens between a magnetic monopole and an axion string in four dimensions, two

Global anomalies in 8d supergravity
We study gauge and gravitational anomalies of fermions and 2-form fields on eight-dimensional spin manifolds. Possible global gauge anomalies are classified by spin bordism groups Ω 9 spin BG $$ {\varOmega}_9^{\mathrm{spin}}(BG) $$ which we determine by ...

Comments on QCD3 and anomalies with fundamental and adjoint matter
’t Hooft anomaly matching is powerful for constraining the low energy phases of gauge theories. In 3d one common anomaly is the parity anomaly in a T-symmetric theory where one cannot gauge the global symmetry group without breaking the time-reversal ...

Abstract There has been significant and extensive knowledge production in the last four decades regarding pragmatic language impairment (PLI) in children with neurodevelopmental disorders. The evidence contained in this literature, however, is contradictory. The present scoping review (ScR) seeks to disentangle competing explanations of conceptualizing,

Zilch vortical effect for fermions
We consider the notion of zilch current that was recently discussed in the literature as an alternative helicity measure for photons. Developing this idea, we suggest the generalization of the zilch for the systems of fermions.

Mass Hierarchies and Quantum Gravity Constraints in DKMM‐refined KKLT
Abstract We carefully revisit the mass hierarchies for the KKLT scenario with an uplift term from an anti D3‐brane in a strongly warped throat. First, we derive the bound resulting from what is usually termed “the throat fitting into the bulk” directly from the Klebanov‐Strassler geometry.
