Nuclear and electron scattering by neutrinos and dark matter in condensed systems
James B. Dent, Barry A. Friedman, Jayden L. Newstead +1
Low-threshold dark matter detectors, in particular cryogenic detectors based on dielectric materials, are among the best tools for probing sub-GeV dark matter masses. In the coming…
Direct Collapse Black Hole Candidates from Decaying Dark Matter
Yash Aggarwal, James B. Dent, Philip Tanedo +1
Injecting 1-13.6 eV photons into the early universe can suppress the molecular hydrogen abundance and alter the star formation history dramatically enough to produce direct collaps…
t-channel dark matter at the LHC -- a whitepaper
Chiara Arina, Benjamin Fuks, Luca Panizzi +67
This report, summarising work achieved in the context of the LHC Dark Matter Working Group, investigates the phenomenology of -channel dark matter models, spanning minimal setup…
Multi-messenger Probes of Asteroid Mass Primordial Black Holes: Superradiance Spectroscopy, Hawking Radiation, and Microlensing
James B. Dent, Bhaskar Dutta, Tao Xu
Superradiance provides a unique opportunity for investigating dark sectors as well as primordial black holes, which themselves are candidates for dark matter over a wide mass range…
Machine Learning Techniques for Intermediate Mass Gap Lepton Partner Searches at the Large Hadron Collider
Bhaskar Dutta, Tathagata Ghosh, Alyssa Horne +6
We consider machine learning techniques associated with the application of a Boosted Decision Tree (BDT) to searches at the Large Hadron Collider (LHC) for pair-produced lepton par…
Jet SIFT-ing: a new scale-invariant jet clustering algorithm for the substructure era
Andrew J. Larkoski, Denis Rathjens, Jason Veatch +1
We introduce a new jet clustering algorithm named SIFT (Scale-Invariant Filtered Tree) that maintains the resolution of substructure for collimated decay products at large boosts.…
Low-Mass dark matter (in)direct detection with inelastic scattering
Nicole F. Bell, James B. Dent, Bhaskar Dutta +2
We revisit the detection of luminous dark matter in direct detection experiments. In this scenario, dark matter scatters endothermically to produce an excited state, which decays t…
Sensitivity to Dark Sector Scales from Gravitational Wave Signatures
James B. Dent, Bhaskar Dutta, Sumit Ghosh +2
We consider gravitational wave signals produced by a first-order phase transition in a theory with a generic renormalizable thermal effective potential of power law form. We find t…
Observing the Migdal effect from nuclear recoils of neutral particles with liquid xenon and argon detectors
Nicole F. Bell, James B. Dent, Rafael F. Lang +2
In recent years, dark matter direct detection experiments have spurred interest in the Migdal effect, where it is employed to extend their sensitivity to lower dark matter masses.…
Cosmic-ray upscattered inelastic dark matter
Nicole F. Bell, James B. Dent, Bhaskar Dutta +4
Light non-relativistic components of the galactic dark matter halo elude direct detection constraints because they lack the kinetic energy to create an observable recoil. However,…
Pathfinder for a High Statistics Search for Missing Energy In Gamma Cascades
James B. Dent, Bhaskar Dutta, Andrew Jastram +7
We investigate the feasibility of a high statistics experiment to search for invisible decay modes in nuclear gamma cascades using 200 kg of %36 Cs(Tl) scintillators that are prese…
Solar Gamma Ray Constraints on Dark Matter Annihilation to Secluded Mediators
Nicole F. Bell, James B. Dent, Isaac W. Sanderson
We consider the indirect detection of dark matter that is captured in the Sun and subsequently annihilates to long-lived dark mediators. If these mediators escape the Sun before de…
Low-mass inelastic dark matter direct detection via the Migdal effect
Nicole F. Bell, James B. Dent, Bhaskar Dutta +3
We consider searches for the inelastic scattering of low-mass dark matter at direct detection experiments, using the Migdal effect. We find that there are degeneracies between the…
Gamma Ray Signals from Cosmic Ray Scattering on Axion-Like Particles
James B. Dent, Bhaskar Dutta, Jayden L. Newstead +4
Dark Matter (DM) may be comprised of axion-like particles (ALPs) with couplings to photons and the standard model fermions. In this paper we study photon signals arising from cosmi…
Present and future status of light dark matter models from cosmic-ray electron upscattering
James B. Dent, Bhaskar Dutta, Jayden L. Newstead +2
Non-relativistic Dark Matter (DM) can be accelerated by scattering on high-energy cosmic-ray (CR) electrons. This process leads to a sub-population of relativistic or semi-relativi…
Flipped Quartification and a composite -quark
James B. Dent, Thomas W. Kephart, Heinrich Päs +1
An alternative "flipped" version of the quartification model is obtained by rearrangement of the particle assignments. The model has two standard (trinification) families and one f…
Measuring the polarization of boosted, hadronic bosons with jet substructure observables
Songshaptak De, Vikram Rentala, William Shepherd
In this work, we present a new technique to measure the longitudinal and transverse polarization fractions of hadronic decays of boosted bosons. We introduce a new jet substruc…
Shift-Type SMEFT Effects in Dileptons at the LHC
Alyssa Horne, Jordan Pittman, Marcus Snedeker +2
We explore the constraints which can be derived on Wilson coefficients in the Standard Model Effective Field Theory from dilepton production, notably including the constraints on o…
Inverse Primakoff Scattering as a Probe of Solar Axions at Liquid Xenon Direct Detection Experiments
James B. Dent, Bhaskar Dutta, Jayden L. Newstead +1
We show that XENON1T and future liquid xenon (LXe) direct detection experiments are sensitive to axions through the standard operators due to inverse-Primakoff…
Explaining the XENON1T excess with Luminous Dark Matter
Nicole F. Bell, James B. Dent, Bhaskar Dutta +3
We show that the excess in electron recoil events seen by the XENON1T experiment can be explained by relatively low-mass Luminous Dark Matter candidate. The dark matter scatters in…

Rafael Aoude, Tobias Hurth, Sophie Renner +1
We investigate the information that can be gained by including flavour data in fits of the Standard Model Effective Field Theory (SMEFT) with the assumption of Minimal Flavour Viol…
New Directions for Axion Searches via Scattering at Reactor Neutrino Experiments
James B. Dent, Bhaskar Dutta, Doojin Kim +4
Searches for pseudoscalar axion-like-particles (ALPs) typically rely on their decay in beam dumps or their conversion into photons in haloscopes and helioscopes. We point out a new…
