Could electron-top interactions spoil the measurement of the Higgs trilinear? -A quantitative estimate at future lepton colliders-
Lukas Allwicher, Christophe Grojean, Lucine Tabatt
The measurement of the Higgs self-coupling is considered the next milestone in the study of the Higgs boson properties. At future facilities below the double Higgs product…
Techniques for mass peak reconstruction in Searches for Long-Lived Heavy Neutral Leptons Decaying to a Lepton and a \(ρ\) Meson
Marzieh Bahmani, Alessandro Guida, Maral Khandan +2
The precise reconstruction of the mass peak of long-lived heavy neutral leptons (HNLs) helps to improve the sensitivity for sterile neutrino searches in both fixed-target and colli…
A Superalgebra Within: representations of lightest standard model particles form a -graded algebra
N. Furey
It is demonstrated how a set of particle representations, familiar from the Standard Model, collectively form a superalgebra. Those representations mirroring the internal behaviour…
Three Generations and a Trio of Trialities
N. Furey, M. J. Hughes
We identify the Standard Model's internal symmetries within the triality symmetries $\mathfrak{tri}(\mathbb{C}) \opl…
A computation of two-loop six-point Feynman integrals in dimensional regularization
Johannes M. Henn, Antonela Matijašić, Julian Miczajka +3
We compute three families of two-loop six-point massless Feynman integrals in dimensional regularization, namely the double-box, the pentagon-triangle, and the hegaxon-bubble famil…
An Algebraic Roadmap of Particle Theories, Part III: Intersections
N. Furey
In this article, we bypass the detailed symmetry breaking pathways established in [1]. Instead, a direct route from the Spin(10) model to the Standard Model is enabled via a single…
An Algebraic Roadmap of Particle Theories, Part II: Theoretical checkpoints
N. Furey
An optimal algebraic model of particle physics has a number of checkpoints to pass. As a minimum, models should conform to the Coleman-Mandula theorem (or estab…
An Algebraic Roadmap of Particle Theories, Part I: General construction
N. Furey
Expanding the results of [1], [2], [3], we demonstrate a network of algebraic connections between six well-known particle theories. These are the Spin(10) model, the Georgi-Glashow…
ALPs, the on-shell way
Enrico Bertuzzo, Christophe Grojean, Gabriel M. Salla
We study how the coupling between axion-like particles (ALPs) and matter can be obtained at the level of on-shell scattering amplitudes. We identify three conditions that allow us…
Opportunistic CP Violation
Quentin Bonnefoy, Emanuele Gendy, Christophe Grojean +1
In the electroweak sector of the Standard Model, CP violation arises through a very particular interplay between the three quark generations, as described by the Cabibbo--Kobayashi…
QuantumFDTD -- A computational framework for the relativistic Schrödinger equation
Rafael L. Delgado, Sebastian Steinbeißer, Michael Strickland +1
We extend the publicly available quantumfdtd code. It was originally intended for solving the time-independent three-dimensional Schrödinger equation via the finite-difference time…
Numerical evaluation of the nonlinear Gribov-Levin-Ryskin-Mueller-Qiu evolution equations for nuclear parton distribution functions
J. Rausch, V. Guzey, M. Klasen
We numerically study for the first time the nonlinear GLR-MQ evolution equations for nuclear parton distribution function (nPDFs) to next-to-leading order accuracy and quantify the…
Division algebraic symmetry breaking
N. Furey, M. J. Hughes
Reframing certain well-known particle models in terms of normed division algebras leads to two new results for BSM physics. (1) We identify a sequence of complex structures which i…
One generation of standard model Weyl representations as a single copy of
N. Furey, M. J. Hughes
Peering in from the outside, looks to be an ideal mathematical structure for particle physics. It is 3…
Revisiting at the LHC and FCC-hh
Fady Bishara, Philipp Englert, Christophe Grojean +2
Diboson production processes provide good targets for precision measurements at present and future hadron colliders. We consider production, focusing on the de…
Machine learning the trilinear and light-quark Yukawa couplings from Higgs pair kinematic shapes
Lina Alasfar, Ramona Gröber, Christophe Grojean +2
Revealing the Higgs pair production process is the next big challenge in high energy physics. In this work, we explore the use of interpretable machine learning and cooperative gam…
The shift-invariant orders of an ALP
Quentin Bonnefoy, Christophe Grojean, Jonathan Kley
It is generally believed that global symmetries, in particular axion shift symmetries, can only be approximate. This motivates us to quantify the breaking of the shift invariance t…
Interpretable machine learning in Physics
Christophe Grojean, Ayan Paul, Zhuoni Qian +1
Adding interpretability to multivariate methods creates a powerful synergy for exploring complex physical systems with higher order correlations while bringing about a degree of cl…
Violation of custodial symmetry from W-boson mass measurements
Ayan Paul, Mauro Valli
The new measurement of the -boson mass from the CDF collaboration shows a significant tension with the Standard Model prediction. We quantify this discrepancy within a state-of-…
Snowmass 2021 whitepaper: Proton structure at the precision frontier
S. Amoroso, A. Apyan, N. Armesto +54
An overwhelming number of theoretical predictions for hadron colliders require parton distribution functions (PDFs), which are an important ingredient of theory infrastructure for…
Higgs probes of top quark contact interactions and their interplay with the Higgs self-coupling
Lina Alasfar, Jorge de Blas, Ramona Gröber
We calculate the dominant contributions of third generation four-quark operators to single-Higgs production and decay. They enter via loop corrections to Higgs decays into gluons,…
Phenomenology of production at the LHC
Simone Alioli, Juan Fuster, Maria Vittoria Garzelli +6
We present phenomenological results for production at the Large Hadron Collider, of interest for designing forthcoming experimental analyses of this process. We foc…
Solving Combinatorial Problems at Particle Colliders Using Machine Learning
Anthony Badea, William James Fawcett, John Huth +3
High-multiplicity signatures at particle colliders can arise in Standard Model processes and beyond. With such signatures, difficulties often arise from the large dimensionality of…
Measuring the stability of fundamental constants with a network of clocks
G. Barontini, L. Blackburn, V. Boyer +41
The detection of variations of fundamental constants of the Standard Model would provide us with compelling evidence of new physics, and could lift the veil on the nature of dark m…
