MeV Dark Matter with MeV Dark Photons in Abelian Kinetic Mixing Theories
Federico Compagnin, Stefano Profumo, Nicolao Fornengo
We consider the cosmology and phenomenology of a dark photon portal to a simple dark sector consisting of a single, light, fermionic dark matter particle species with mass in the M…
Reduced Axion Abundance from an Extended Symmetry
Itamar J. Allali, Mark P. Hertzberg, Yi Lyu
In recent work we showed that the relic dark matter abundance of QCD axions can be altered when the Peccei-Quinn (PQ) field is coupled to very light scalar/s, rendering the effecti…
Optimizing pixel tracklet searches for shorter lifetimes
Matthew Gignac, Can Kilic, Rakhi Mahbubani +1
Pixel tracklets, disappearing tracks reconstructed with only pixel hits, have proven to be a promising technique in LHC analyses to search for dark matter candidates at the LHC tha…
Millicharged Relics Reveal Massless Dark Photons
Asher Berlin, Jeff A. Dror, Xucheng Gan +1
The detection of massless kinetically-mixed dark photons is notoriously difficult, as the effect of this mixing can be removed by a field redefinition in vacuum. In this work, we s…
On the Sensitivity of Spin-Precession Axion Experiments
Jeff A. Dror, Stefania Gori, Jacob M. Leedom +1
A leading direction in the hunt for axion dark matter is to search for its influence on nuclear spins. The detection scheme involves polarizing a sample of nuclei within a strong s…
Dark Sector Physics at High-Intensity Experiments
Stefania Gori, Mike Williams, Phil Ilten +10
Is Dark Matter part of a Dark Sector? The possibility of a dark sector neutral under Standard Model (SM) forces furnishes an attractive explanation for the existence of Dark Matter…
New Opportunities for Detecting Axion-Lepton Interactions
Wolfgang Altmannshofer, Jeff A. Dror, Stefania Gori
We revisit the theory and constraints on axion-like particles (ALPs) interacting with leptons. We clarify some subtleties in the constraints on ALP parameter space and find several…
Dark Black Holes in the Mass Gap
Nicolas Fernandez, Akshay Ghalsasi, Stefano Profumo +2
In the standard picture of stellar evolution, pair-instability -- the energy loss in stellar cores due to electron-positron pair production -- is predicted to prevent the collapse…
Hazma Meets HERWIG4DM: Precision Gamma-Ray, Neutrino, and Positron Spectra for Light Dark Matter
Adam Coogan, Logan Morrison, Tilman Plehn +2
We present a new open-source package, Hazma 2, that computes accurate spectra relevant for indirect dark matter searches for photon, neutrino, and positron production from vector-m…
Heavy Neutral Leptons at Beam Dump Experiments of Future Lepton Colliders
Pierce Giffin, Stefania Gori, Yu-Dai Tsai +1
A new beam dump experiment that utilizes the beam of future high energy electron-positron colliders could be an excellent avenue to search for dark sector particles due to its unpr…
P-even, CP-violating Signals in Scalar-Mediated Processes
Howard E. Haber, Venus Keus, Rui Santos
Most studies of Higgs sector CP violation focus on the detection of CP-violating neutral Higgs-fermion Yukawa couplings, which yield P-odd, CP-violating phenomena. There is some li…
First indirect detection constraints on axions in the Solar basin
William DeRocco, Shalma Wegsman, Brian Grefenstette +2
Axions with masses of order keV can be produced in great abundance within the Solar core. The majority of Sun-produced axions escape to infinity, but a small fraction of the flux i…
Altered Axion Abundance from a Dynamical Peccei-Quinn Scale
Itamar J. Allali, Mark P. Hertzberg, Yi Lyu
We build a model in which the relic abundance of axions is altered from the standard misalignment mechanism, either increased or decreased, due to the presence of a new light scala…
Simulation Based Inference for Efficient Theory Space Sampling: an Application to Supersymmetric Explanations of the Anomalous Muon (g-2)
Logan Morrison, Stefano Profumo, Nolan Smyth +1
For the purpose of minimizing the number of sample model evaluations, we propose and study algorithms that utilize (sequential) versions of likelihood-to-evidence ratio neural esti…
Snowmass2021 Cosmic Frontier White Paper: Ultraheavy particle dark matter
Daniel Carney, Nirmal Raj, Yang Bai +25
We outline the unique opportunities and challenges in the search for "ultraheavy" dark matter candidates with masses between roughly and the Planck scale $m_{\rm pl}…
Dark Matter Effective Field Theory and an Application to Vector Dark Matter
Jason Aebischer, Wolfgang Altmannshofer, Elizabeth E. Jenkins +1
The Standard Model Effective Field Theory (SMEFT) and the Low Energy Effective Field Theory (LEFT) can be extended by adding additional spin 0, 1/2 and 1 dark matter particles whic…
New Physics Searches at Kaon and Hyperon Factories
Evgueni Goudzovski, Diego Redigolo, Kohsaku Tobioka +61
Rare meson decays are among the most sensitive probes of both heavy and light new physics. Among them, new physics searches using kaons benefit from their small total decay widths…
Dark matter scattering in astrophysical media: collective effects
William DeRocco, Marios Galanis, Robert Lasenby
It is well-known that stars have the potential to be excellent dark matter detectors. Infalling dark matter that scatters within stars could lead to a range of observational signat…
