Prospects for detecting axionlike particles at the Coherent CAPTAIN-Mills experiment

A. A. Aguilar-Arevalo, D. S. M. Alves, S. Biedron +45

We show results from the Coherent CAPTAIN Mills (CCM) 2019 engineering run which begin to constrain regions of parameter space for axion-like particles (ALPs) produced in electroma…

Chiral models of composite axions and accidental Peccei-Quinn symmetry

Roberto Contino, Alessandro Podo, Filippo Revello

We introduce a class of composite axion models that provide a natural solution to the strong CP problem, and possibly account for the observed dark matter abundance. The QCD axion…

Probing parton saturation and the gluon dipole via diffractive jet production at the Electron-Ion Collider

E. Iancu, A. H. Mueller, D. N. Triantafyllopoulos

We demonstrate that hard dijet production via coherent inelastic diffraction is a promising channel for probing gluon saturation at the Electron-Ion Collider. By diffra…

Shear viscosity at finite baryon densities

Emma McLaughlin, Jacob Rose, Travis Dore +3

We use the excluded volume Hadron Resonance Gas (HRG) model with the most up-to-date hadron list to calculate at low temperatures and at finite baryon densities . This…

High-dimensional Anomaly Detection with Radiative Return in Collisions

Julia Gonski, Jerry Lai, Benjamin Nachman +1

Experiments at a future collider will be able to search for new particles with masses below the nominal centre-of-mass energy by analyzing collisions with initial-stat…

Anomalous Jet Identification via Sequence Modeling

Alan Kahn, Julia Gonski, Inês Ochoa +2

This paper presents a novel method of searching for boosted hadronically decaying objects by treating them as anomalous elements of a contaminated dataset. A Variational Recurrent…

Explaining the MiniBooNE Excess Through a Mixed Model of Oscillation and Decay

Stefano Vergani, Nicholas W. Kamp, Alejandro Diaz +4

The electron-like excess observed by the MiniBooNE experiment is explained with a model comprising a new low mass state ( eV) participating in neutrino oscillations…

Analytical asymptotics for hard diffraction

Anh Dung Le, Alfred H. Mueller, Stéphane Munier

We show that the cross section for diffractive dissociation of a small onium off a large nucleus at total rapidity and requiring a minimum rapidity gap can be…

The LHC Olympics 2020: A Community Challenge for Anomaly Detection in High Energy Physics

Gregor Kasieczka, Benjamin Nachman, David Shih +44

A new paradigm for data-driven, model-agnostic new physics searches at colliders is emerging, and aims to leverage recent breakthroughs in anomaly detection and machine learning. I…
