On the associativity of 1-loop corrections to the celestial operator product in gravity
Journal of High Energy Physics, 2023 The question of whether the holomorphic collinear singularities of graviton amplitudes define a consistent chiral algebra has garnered much recent attention.

Anomaly Cancellation in Supergravity with Fayet-Iliopoulos Couplings [PDF]
, 2006 We review and clarify the cancellation conditions for gauge anomalies which occur when N=1, D=4 supergravity is coupled to a Kahler non-linear sigma-model with gauged isometries and Fayet-Iliopoulos couplings.

Exploring 2-group global symmetries
Journal of High Energy Physics, 2019 We analyze four-dimensional quantum field theories with continuous 2-group global symmetries. At the level of their charges, such symmetries are identical to a product of continuous flavor or spacetime symmetries with a 1-form global symmetry U(1) B (1) ,

D-Branes in the Green-Schwarz Formalism [PDF]
, 1999 We give a basic account of supersymmetric open strings and D-branes using the Green-Schwarz formalism, obtaining a manifestly spacetime supersymmetric description of their spectrum.

Metric-independent measures for supersymmetric extended object theories on curved backgrounds
Physics Letters B, 2014 For Green–Schwarz superstring σ-model on curved backgrounds, we introduce a non-metric measure Φ≡ϵijϵIJ(∂iφI)(∂jφJ) with two scalars φI(I=1,2) used in ‘Two-Measure Theory’ (TMT). As in the flat-background case, the string tension T=(2πα′)−1 emerges as an

Nuclear Physics B, 2018 We use Pauli–Villars regularization to evaluate the conformal and chiral anomalies in the effective field theories from Z3 and Z7 compactifications of the heterotic string without Wilson lines.

Chiral anomalies on a circle and their cancellation in F-theory
Journal of High Energy Physics, 2018 We study in detail how four-dimensional local anomalies manifest themselves when the theory is compactified on a circle. By integrating out the Kaluza-Klein modes in a way that preserves the four-dimensional symmetries in the UV, we show that the three ...

Anomaly Structure of Supergravity and Anomaly Cancellation [PDF]
, 2009 We display the full anomaly structure of supergravity, including new D-term contributions to the conformal anomaly. This expression has the super-Weyl and chiral U(1)_K transformation properties that are required for implementation of the Green-Schwarz ...

Gauge and gravitational anomalies in D=4 N=1 orientifolds [PDF]
, 1999 The cancellation of U(1)-gauge and U(1)-gravitational anomalies in certain D=4 N=1 Type IIB orientifolds is analyzed in detail, from a string theory point of view.

A new look at anomaly cancellation in heterotic $M$-theory [PDF]
, 2005 This paper considers anomaly cancellation for eleven-dimensional supergravity on a manifold with boundary and theories related to heterotic $M$-theory. The Green-Schwarz mechanism is implemented without introducing distributions.
