Dark Matter EFT Landscape Probed by QUEST-DMC
DMC Collaboration, N. Darvishi, S. Autti +27
We present the projected sensitivity to non-relativistic Effective Field Theory (EFT) operators for Dark Matter (DM) direct detection using the QUEST-DMC experiment. QUEST-DMC empl…
Fermionic sub-GeV Dark Matter from evaporating Primordial Black Holes at DarkSide-50
50 Collaboration, P. Agnes, I. F. Albuquerque +125
We present a search for boosted dark matter from Primordial Black Holes (PBH) evaporation using the DarkSide-50 ionization-signal-only dataset corresponding to the experiment's ($1…
Dark Matter Attenuation Effects: Sensitivity Ceilings for Spin-Dependent and Spin-Independent Interactions
DMC Collaboration, N. Darvishi, J. Smirnov +27
Direct detection experiments aimed at uncovering the elusive nature of dark matter (DM) have made significant progress in probing ever lower cross-sections for DM-nucleon interacti…
Automated Ring-Diagram Framework for Classifying CP Invariants
Neda Darvishi, Yining Wang, Jiang-Hao Yu
In this study, we introduce a transformative, automated framework for classifying basis invariants in generic field theories. Utilising a novel ring-diagram methodology accompanied…
Introducing the concept of the Widom line in the QCD phase diagram
G. Sordi, A. -M. S. Tremblay
Critical phenomena emerging from the critical end point of a first-order transition are ubiquitous in nature. Here we bring the concept of a supercritical crossover, the Widom line…
Maximising CP Violation in Naturally Aligned Two-Higgs Doublet Models
Neda Darvishi, Apostolos Pilaftsis, Jiang-Hao Yu
The Two-Higgs Doublet Model (2HDM) is a well-motivated theoretical framework that provides additional sources of CP Violation (CPV) beyond the Standard Model (SM). After studying t…
Higgs interference effects in top-quark pair production in the 1HSM
Andrea Banfi, Nikolas Kauer, Alexander Lind +2
We present a next-to-leading-order (NLO) study of the process in the 1-Higgs-singlet extension of the Standard Model with an addition…
Dark Matter and Neutrino Masses in a Portalino-like Model
Dugald Hepburn, Stephen M. West
We explore a Portalino-like model of dark matter and neutrino masses in which right-handed neutrino fields connect gauge neutral operators from the Standard Model and Hidden Sector…
Dark Photon Stars: Formation and Role as Dark Matter Substructure
Marco Gorghetto, Edward Hardy, John March-Russell +2
Any new vector boson with non-zero mass (a `dark photon' or `Proca boson') that is present during inflation is automatically produced at this time from vacuum fluctuations and can…
A substandard candle: the low- method at few-GeV neutrino energies
Callum Wilkinson, Stephen Dolan, Luke Pickering +1
As accelerator-neutrino oscillation experiments improve oscillation parameter constraints, control over systematic uncertainties on the incoming neutrino flux and interaction model…
Event Generators for High-Energy Physics Experiments
J. M. Campbell, M. Diefenthaler, T. J. Hobbs +209
We provide an overview of the status of Monte-Carlo event generators for high-energy particle physics. Guided by the experimental needs and requirements, we highlight areas of acti…
Off-shell Higgs Interpretations Task Force: Models and Effective Field Theories Subgroup Report
Aleksandr Azatov, Jorge de Blas, Adam Falkowski +8
This report presents the results of the Models and Effective Field Theories Subgroup of the Off-Shell Interpretations Task Force in the LHC Higgs Working Group. The main goal of th…
Publishing statistical models: Getting the most out of particle physics experiments
Kyle Cranmer, Sabine Kraml, Harrison B. Prosper +30
The statistical models used to derive the results of experimental analyses are of incredible scientific value and are essential information for analysis preservation and reuse. In…
Effect of Systematic Uncertainty Estimation on the Muon Anomaly
Glen Cowan
The statistical significance that characterizes a discrepancy between a measurement and theoretical prediction is usually calculated assuming that the statistical and systematic un…
Feebly-Interacting Particles:FIPs 2020 Workshop Report
Prateek Agrawal, Martin Bauer, James Beacham +43
With the establishment and maturation of the experimental programs searching for new physics with sizeable couplings at the LHC, there is an increasing interest in the broader part…
BSM WW production with a jet veto
Luke Arpino, Andrea Banfi, Sebastian Jäger +1
We consider the impact on WW production of the unique dimension-six operator coupling gluons to the Higgs field. In order to study this process, we have to appropriately model the…
Higgs interference effects at the one-loop level in the 1-Higgs-Singlet extension of the Standard Model
Nikolas Kauer, Alexander Lind, Philipp Maierhöfer +1
A detailed study of Higgs interference effects at the one-loop level in the 1-Higgs-Singlet extension of the Standard Model (1HSM) is presented for the WW and tt decay modes with f…
Long-Lived Particles at the Energy Frontier: The MATHUSLA Physics Case
David Curtin, Marco Drewes, Matthew McCullough +85
We examine the theoretical motivations for long-lived particle (LLP) signals at the LHC in a comprehensive survey of Standard Model (SM) extensions. LLPs are a common prediction of…
