Classical symmetries -- three ways -- and a precision holography check

Silvia Georgescu, Monica Guica

The deformation is a fully tractable irrelevant deformation of two-dimensional CFTs, which yields a UV-complete QFT that is local and conformal along one lightlike direct…

Tail effects of self-interacting scalar fields

Philippe Brax, Emma Bruyère

We consider the effects of quartic self-interactions on the dynamics of a binary system due to a (nearly) massless scalar field conformally coupled to matter. We investigate the de…

Secondary Lund jet plane as a gluon enriched sample

Cristian Baldenegro, Alba Soto-Ontoso, Gregory Soyez

We propose a new strategy to obtain a high-purity sample of gluon-initiated jets at the LHC. Our approach, inspired by the Lund jet plane picture, is to perform a dijet selection w…

SymTFTs and Non-Invertible Symmetries of 6d (2,0) SCFTs of Type from M-theory

Federico Bonetti, Michele Del Zotto, Ruben Minasian

We revisit 6d (2,0) SCFTs of type and their realization in M-theory, focusing on absolute variants of these theories and on their global finite 0- and 2-form symmetries. We d…

Two-photon correlations and HOM visibility from an imperfect single-photon source

Eva M. González-Ruiz, Johannes Bjerlin, Oliver August Dall'Alba Sandberg +1

We study the single photon purity of a resonantly driven single-photon source in the realistic scenario where the excitation laser can leak into the detection path. We find that th…

Amplitudes for Hawking Radiation

Rafael Aoude, Donal O'Connell, Matteo Sergola

We obtain the Hawking spectrum by exponentiating a series of Feynman diagrams describing a scalar field scattering through a collapse background. Our approach is rooted in semiclas…
