Restrictions for $n$ -Point Vertices in Higher-Spin Theories

Stefan Fredenhagen, Olaf Krüger, Karapet Mkrtchyan

We give a simple classification of the independent $n$ -point interaction vertices for bosonic higher-spin gauge fields in $d$ -dimensional Minkowski space-times. We first give a cha…

On Critical Exponents for Self-Similar Collapse

Riccardo Antonelli, Ehsan Hatefi

We explore systematically perturbations of self-similar solutions to the Einstein-axion-dilaton system, whose dynamics are invariant under spacetime dilations combined with interna…

On self-similar axion-dilaton configurations

Riccardo Antonelli, Ehsan Hatefi

We explore self-similar collapse solutions to the Einstein-axion-dilaton system in arbitrary spacetime dimensions, which are invariant under spacetime dilation combined with intern…

Gauging 1-form center symmetries in simple $S U (N)$ gauge theories

Stefano Bolognesi, Kenichi Konishi, Andrea Luzio

Consequences of gauging exact $Z_{k}^{C}$ center symmetries in several simple $S U (N)$ gauge theories, where $k$ is a divisor of $N$ , are investigated. Models discussed include: the $SU…

Brane annihilation in non-supersymmetric strings

Riccardo Antonelli, Ivano Basile

In this paper we study non-perturbative instabilities in Anti de-Sitter vacua arising from flux compactifications of string models with broken supersymmetry. In the semi-classical…

On electromagnetic and colour memory in even dimensions

Andrea Campoleoni, Dario Francia, Carlo Heissenberg

We explore memory effects associated to both Abelian and non-Abelian radiation getting to null infinity, in arbitrary even spacetime dimensions. Together with classical memories, l…

All Order $α^{'}$ Corrections to Fermionic Couplings of D-brane-Anti-D-brane Effective Actions

Ehsan Hatefi

We first point out to all order $α^{'}$ corrections to lower order fermionic couplings and their effective actions of type II super string theory. In order to reveal all symmetries of…

To the sphere and back again: de Sitter infrared correlators at NTLO in 1/N

Diana López Nacir, Francisco D. Mazzitelli, Leonardo G. Trombetta

We analyze the infrared behavior of the two and four-point functions for the massless $O (N)$ model in Lorentzian de Sitter spacetime, using the $1/ N$ expansion. Our approach is bas…

On All-Order Higher-Point $D p$ - $D p$ Effective Actions

Riccardo Antonelli, Ivano Basile, Ehsan Hatefi

In this paper we derive a class of contributions to all orders in $α^{'}$ to the effective action of D-brane-anti D-brane systems in Type II String Theory, considering an amplitude in…
