The discrete Green-Schwarz mechanism in 6D F-theory and elliptic genera of non-critical strings [PDF]
We study global anomalies of discrete gauge symmetries in six-dimensional supergravities and their realizations in F-theory. We explicitly construct a discrete Green-Schwarz mechanism that depends on the choice of a coupling constant and on a certain ...

The Green-Schwarz mechanism and geometric anomaly relations in 2d (0,2) F-theory vacua [PDF]
We study the structure of gauge and gravitational anomalies in 2d N = (0, 2) theories obtained by compactification of F-theory on elliptically fibered Calabi-Yau 5-folds. Abelian gauge anomalies, induced at 1-loop in perturbation theory, are cancelled by

$\gamma-$ray line generated by the Green-Schwarz mechanism [PDF]
We study the phenomenology of a $U_X(1)$ extension of the Standard Model where the SM particles are not charged under the new abelian group. The Green-Schwarz mechanism insures that the model is anomaly free. The erstwhile invisible dark gauge field $X$,

Probing the Green-Schwarz Mechanism at the Large Hadron Collider [PDF]
We investigate the phenomenology of new abelian gauge bosons, which we denote as $X$ bosons, that suffer a mixed anomaly with the Standard Model, but are made self-consistent by the Green-Schwarz mechanism.

Dynamical supersymmetry breaking in models with a Green-Schwarz mechanism [PDF]
We consider supersymmetry breaking in theories with gaugino condensation in the presence of an anomalous U(1) symmetry with anomaly cancellation by the Green-Schwarz mechanism.

Generalized Green-Schwarz mechanism in F theory [PDF]
We derive the anomaly 8-form of 6-dimensional gauge theories arising in F theory compactifications on elliptic Calabi-Yau threefolds. The result allows to determine the matter content of certain such theories in terms of intersection numbers on the base ...

Vector/tensor duality in the five dimensional supersymmetric Green-Schwarz mechanism [PDF]
The five dimensional version of the Green-Schwarz mechanism can be invoked to cancel U(1) anomalies on the boundaries of brane world models. In five dimensions there are two dual descriptions that employ either a two-form tensor field or a vector field ...

A Note on the Green - Schwarz Mechanism in Open - String Theories [PDF]
An interesting feature of some open superstring models in $D < 10$ is the simultaneous presence, in the spectrum, of gauge fields and of a number of antisymmetric tensor fields. In these cases the Green-Schwarz mechanism can (and does) take a generalized

Unitarity Bounds for Gauged Axionic Interactions and the Green-Schwarz Mechanism [PDF]
We analyze the effective actions of anomalous models in which a four-dimensional version of the Green-Schwarz mechanism is invoked for the cancellation of the anomalies, and we compare it with those models in which gauge invariance is restored by the ...
