Towards the ultimate differential SMEFT analysis
Shankha Banerjee, Rick S. Gupta, Joey Y. Reiness +2
We obtain SMEFT bounds using an approach that utilises the complete multi-dimensional differential information of a process. This approach is based on the fact that at a given EFT…
On the Wondrous Stability of ALP Dark Matter
Gonzalo Alonso-Álvarez, Rick S. Gupta, Joerg Jaeckel +1
The very low mass and small coupling of axion-like particles (ALPs) is usually taken as a guarantor of their cosmological longevity, making them excellent dark matter candidates. T…
Computing Tools for the SMEFT
Editors, :, Jason Aebischer +22
The increasing interest in the phenomenology of the Standard Model Effective Field Theory (SMEFT), has led to the development of a wide spectrum of public codes which implement aut…
Higgs boson potential at colliders: status and perspectives
B. Di Micco, M. Gouzevitch, J. Mazzitelli +104
This document summarises the current theoretical and experimental status of the di-Higgs boson production searches, and of the direct and indirect constraints on the Higgs boson se…
Probing new physics using Rydberg states of atomic hydrogen
Matthew P. A. Jones, Robert M. Potvliege, Michael Spannowsky
We consider the role of high-lying Rydberg states of simple atomic systems such as H in setting constraints on physics beyond the Standard Model. We obtain highly accurate boun…
Higgs phenomenology as a probe of sterile neutrinos
Jonathan M. Butterworth, Mikael Chala, Christoph Englert +2
Physics beyond the Standard Model can manifest itself as both new light states and heavy degrees of freedom. In this paper, we assume that the former comprise only a sterile neutri…
Towards a generic implementation of matrix-element maximisation as a classifier in particle physics
Stefan von Buddenbrock, Olivier Mattelaer, Michael Spannowsky
The so-called matrix-element method (MEM) has long been used successfully as a classification tool in particle physics searches. In the presence of invisible final state particles,…
Novel -decay signatures of light scalars at high energy facilities
Andrew Blance, Mikael Chala, Maria Ramos +1
We study the phenomenology of light scalars of masses and coupling to heavy flavour-violating vector bosons of mass . For few GeV, this scenario…
Constraining strongly coupled new physics from cosmic rays with machine learning techniques
Peter Schichtel, Michael Spannowsky, Philip Waite
Cosmic rays interacting with the atmosphere allow for the probing of fundamental interactions at ultra-high energies. We thus obtain limits on strongly coupled new physics models v…
Adversarially-trained autoencoders for robust unsupervised new physics searches
Andrew Blance, Michael Spannowsky, Philip Waite
Machine learning techniques in particle physics are most powerful when they are trained directly on data, to avoid sensitivity to theoretical uncertainties or an underlying bias on…
Resolving the tensor structure of the Higgs coupling to -bosons via Higgs-strahlung
Shankha Banerjee, Rick S. Gupta, Joey Y. Reiness +1
We propose differential observables for that can be used to completely determine the tensor structure of the couplings releva…
Mapping the shape of the scalar potential with gravitational waves
Mikael Chala, Valentin V. Khoze, Michael Spannowsky +1
We study the dependence of the observable stochastic gravitational wave background induced by a first-order phase transition on the global properties of the scalar effective potent…
Revisiting the channel at the FCC-hh
Shankha Banerjee, Frank Krauss, Michael Spannowsky
The exploration of the scalar sector of the Standard Model is at the core of current and future science programs at collider experiments, with increasing focus on the self-interact…
Searching new physics in rare -meson decays into multiple muons
Mikael Chala, Ulrik Egede, Michael Spannowsky
New heavy vector bosons and light scalars are predicted in a plethora of models of new physics. In particular, in new strongly interacting sectors they play the role of the and…
All-in-one Relaxion, a unified solution to five BSM puzzles
R. S. Gupta, J. Y. Reiness, M. Spannowsky
We present a unified relaxion solution to the five major outstanding issues in particle physics: the hierarchy problem, dark matter, matter-antimatter asymmetry, neutrino masses an…
Solving differential equations with neural networks: Applications to the calculation of cosmological phase transitions
Maria Laura Piscopo, Michael Spannowsky, Philip Waite
Starting from the observation that artificial neural networks are uniquely suited to solving optimisation problems, and most physics problems can be cast as an optimisation task, w…
A fresh look at ALP searches in fixed target experiments
Lucian Harland-Lang, Joerg Jaeckel, Michael Spannowsky
A significant number of high power proton beams are available or will go online in the near future. This provides exciting opportunities for new fixed target experiments and the se…
HYTREES: Combining Matrix Elements and Parton Shower for Hypothesis Testing
Stefan Prestel, Michael Spannowsky
We present a new way of performing hypothesis tests on scattering data, by means of a perturbatively calculable classifier. This classifier exploits the "history tree" of how the m…
Looking inside jets: an introduction to jet substructure and boosted-object phenomenology
Simone Marzani, Gregory Soyez, Michael Spannowsky
The study of the internal structure of hadronic jets has become in recent years a very active area of research in particle physics. Jet substructure techniques are increasingly use…
Approaching robust EFT limits for CP-violation in the Higgs sector
Christoph Englert, Peter Galler, Andrew Pilkington +1
Constraining CP-violating interactions in effective field theory (EFT) of dimension six faces two challenges. Firstly, degeneracies in the multi-dimensional space of Wilson coeffic…
