Deconfinement on and Axion Domain Walls
Paolo Bilisco, Raffaele Tito D'Agnolo, Arthur Platschorre +1

Landscapes at Colliders
Raffaele Tito D'Agnolo, Manuel Ettengruber, Lian-Tao Wang
Theories with a large number of long-lived metastable vacua are our only concrete explanation for the puzzling value of the Cosmological Constant (CC). The energy scales where thes…
The Intrinsic Dimension of Collider Events and Model-Independent Searches in 100 Dimensions
Raffaele Tito D'Agnolo, Alfredo Glioti, Gabriele Rigo +1
The phase space of hadron collider events spans hundreds of dimensions, generating an intricate geometry that we are just starting to explore. The number of possible new physics si…
Weak Scale Triggers in the SMEFT
Pier Giuseppe Catinari, Raffaele Tito D'Agnolo, Pablo Sesma
There are no weak scale triggers in the SMEFT up to dimension six that can solve the hierarchy problem far above the weak scale. Our arguments can be used to show that the same is…
A Prototype Hybrid Mode Cavity for Heterodyne Axion Detection
Zenghai Li, Kevin Zhou, Marco Oriunno +7
In the heterodyne approach to axion detection, axion dark matter induces transitions between two modes of a microwave cavity, resulting in a parametrically enhanced signal power. W…
Summary Report of the Physics Beyond Colliders Study at CERN
R. Alemany Fernández, M. Au, G. Arduini +80
The Physics Beyond Collider (PBC) Study Group was initially mandated by the CERN Management to prepare the previous European Particle Physics Strategy Update for CERN projects othe…
Classical (and Quantum) Heuristics for Gravitational Wave Detection
Raffaele Tito D'Agnolo, Sebastian A. R. Ellis
We derive a lower bound on the sensitivity of generic mechanical and electromagnetic gravitational wave detectors. We consider both classical and quantum detection schemes, althoug…
A Cosmological Solution to the Doublet-Triplet Splitting Problem
Csaba Csaki, Raffaele Tito D'Agnolo, Eric Kuflik +1
We propose a model that provides a simultaneous solution to the doublet-triplet splitting problem of grand unified theories, the electroweak hierarchy problem and the strong CP pro…
A Multiverse Outside of the Swampland
Raffaele Tito D'Agnolo, Paolo Mangini, Gabriele Rigo +1
A Multiverse can arise from landscapes without de Sitter minima. It can be populated during a period of eternal inflation without trans-Planckian field excursions and without flat…
Instanton NDA and Applications to Axion Models
Csaba Csáki, Raffaele Tito D'Agnolo, Eric Kuflik +1
We present a simple set of power counting rules which allows us to easily estimate calculable instanton effects up to factors. We apply the resulting Instanton NDA to examin…

Csaba Csáki, Raffaele Tito D'Agnolo, Rick S. Gupta +3
We investigate the dynamics responsible for generating the potential of the , the (would-be) Goldstone boson associated with the anomalous axial symmetry of QCD. The sta…
Signals of Millicharged Dark Matter in Light-Shining-Through-Wall Experiments
Asher Berlin, Raffaele Tito D'Agnolo, Sebastian A. R. Ellis +1
We discuss a novel detection technique for millicharged dark matter that makes use of existing light-shining-through-wall (LSW) experiments searching for massive dark photons. Sinc…
The Two Scales of New Physics in Higgs Couplings
Raffaele Tito D'Agnolo, Florian Nortier, Gabriele Rigo +1
Higgs coupling deviations from Standard Model predictions contain information about two scales of Nature: that of new physics responsible for the deviation, and the scale where new…
MAGO2.0: Electromagnetic Cavities as Mechanical Bars for Gravitational Waves
