Anomaly inflow and gauge group topology in the 10d Sugimoto string theory

Journal of High Energy Physics
We revisit the chiral spectra on charged 1- and 5-branes in the 10d non-supersymmetric sp 16 $$ \mathfrak{sp}(16) $$ string theory (also known as the Sugimoto model), and verify that they consistently cancel the anomaly inflow induced by a Green-Schwarz ...

Quantum Gravity Bounds on 4D EFTs with Minimal Supersymmetry

, 2023
According to the Swampland idea, quantum gravity effects put severe constraints on effective field theories beyond the usual consistency conditions from quantum field theory such as absence of gauge or gravitational anomalies.

Machine learning the 6d supergravity landscape

Journal of High Energy Physics
In this paper, we apply both supervised and unsupervised machine learning algorithms to the study of the string landscape and swampland in 6-dimensions. Our data are the (almost) anomaly-free 6-dimensional N $$ \mathcal{N} $$ = (1, 0) supergravity models,

Global anomalies, discrete symmetries and hydrodynamic effective actions

, 2019
We derive effective actions for parity-violating fluids in both (3 + 1) and (2 + 1) dimensions, including those with anomalies. As a corollary we confirm the most general constitutive relations for such systems derived previously using other methods.

Two-dimensional gauge anomalies and p-adic numbers

Journal of High Energy Physics
We show how methods of number theory can be used to study anomalies in gauge quantum field theories in spacetime dimension two. To wit, the anomaly cancellation conditions for the abelian part of the local anomaly admit solutions if and only if they ...

String Phenomenology 2019

, 2019
Anomalies are a powerful probe of the dynamics of field theories. In this talk I will discuss how to connect different anomalies in various dimensions, and describe some applications of these ideas in string model ...

The evaluation map in field theory, sigma-models and strings II

, 1988
In this paper, we examine specifically the rôle of the evaluation map in sigma-models and strings. We discuss the difference between sigma-models and field theory, as far as anomaly cancellation is concerned. The introduction of the Wess—Zumino terms in

The absence of global anomalies of CP symmetry

Journal of High Energy Physics
Some solutions to the strong CP problem assume that CP symmetry is a gauge symmetry, which is then spontaneously broken. For this scenario to be possible, the CP symmetry should not have any nonperturbative (global) anomalies.

Quantum field theory of (p,0)-forms on kaehler manifolds [PDF]

In questa tesi abbiamo studiato la quantizzazione di una teoria di gauge di forme differenziali su spazi complessi dotati di una metrica di Kaehler. La particolarità di queste teorie risiede nel fatto che esse presentano invarianze di gauge riducibili ...
