Inelastic Signatures of Electroweak Dark Matter
Juri Smirnov, Spencer Griffith, John F. Beacom
Minimal dark matter extended to include a Majorana and a Dirac multiplet coupled through the Higgs --- the HC-MDM model --- provides a compelling and predictive framework. We show…
The Role of Symmetries in Dark Matter Detector Design
Benjamin Lillard, Jack D. Shergold, Juri Smirnov
Anisotropic materials have emerged as promising candidates for the next generation of sub-GeV dark matter direct detection experiments, because their intrinsic directionality gives…
Linking Leptogenesis and Asymmetric Dark Matter: A Testable Framework for Neutrino Mass and the Matter-Antimatter Asymmetry
Henry G. F. McKenna, Juri Smirnov, Martin Gorbahn
We investigate a minimal extension of the Leptogenesis framework that simultaneously explains the observed baryon asymmetry and dark matter (DM) abundance through the decay of a he…
Evaporation Barrier for Dark Matter in Celestial Bodies
Javier F. Acevedo, Rebecca K. Leane, Juri Smirnov
The minimum testable dark matter (DM) mass for almost all DM signatures in celestial bodies is determined by the rate at which DM evaporates. DM evaporation has previously been cal…
Scalar Co-SIMP Dark Matter: Models and Sensitivities
Aditya Parikh, Juri Smirnov, Weishuang Linda Xu +1
In this work, we present UV completions of the recently proposed number-changing Co-SIMP freeze-out mechanism. In contrast to the standard cannibalistic-type dark matter picture th…
Dark Matter Bound States: A Window into the Early Universe
Juri Smirnov
Despite significant experimental sensitivity to point-like, weakly interacting particles at the electroweak mass scale, dark matter has not been found yet. This could hint at a mor…
White Dwarfs in Dwarf Spheroidal Galaxies: A New Class of Compact-Dark-Matter Detectors
Juri Smirnov, Ariel Goobar, Tim Linden +1
Recent surveys have discovered a population of faint supernovae, known as Ca-rich gap transients, inferred to originate from explosive ignitions of white dwarfs. In addition to the…
Floating Dark Matter in Celestial Bodies
Rebecca K. Leane, Juri Smirnov
Dark matter (DM) can be captured in celestial bodies after scattering and losing sufficient energy to become gravitationally bound. We derive a general framework that describes the…
A Next-Generation Liquid Xenon Observatory for Dark Matter and Neutrino Physics
J. Aalbers, K. Abe, V. Aerne +591
The nature of dark matter and properties of neutrinos are among the most pressing issues in contemporary particle physics. The dual-phase xenon time-projection chamber is the leadi…
Glueballs in a Thermal Squeezeout Model
Pouya Asadi, Eric David Kramer, Eric Kuflik +2
It has been shown that a first order confinement phase transition can drastically change the relic dark matter abundance in confining dark sectors with only heavy dark quarks. We s…
Early-Universe Model Building
Pouya Asadi, Saurabh Bansal, Asher Berlin +37
Theoretical investigations into the evolution of the early universe are an essential part of particle physics that allow us to identify viable extensions to the Standard Model as w…
WIMPs Without Weakness: Generalized Mass Window with Entropy Injection
Pouya Asadi, Tracy R. Slatyer, Juri Smirnov
We study general freeze-out scenarios where an arbitrary number of initial and final dark matter particles participate in the number-changing freeze-out interaction. We consider a…
Accidentally Asymmetric Dark Matter
Pouya Asadi, Eric David Kramer, Eric Kuflik +3
We study the effect of a first-order phase transition in a confining dark sector with heavy dark quarks. The baryons of this sector are the dark matter candidate. During th…
Thermal Squeezeout of Dark Matter
Pouya Asadi, Eric David Kramer, Eric Kuflik +3
We carry out a detailed study of the confinement phase transition in a dark sector with a gauge group and a single generation of dark heavy quark. We focus on heavy enough…
Exoplanets as Sub-GeV Dark Matter Detectors
Rebecca K. Leane, Juri Smirnov
We present exoplanets as new targets to discover Dark Matter (DM). Throughout the Milky Way, DM can scatter, become captured, deposit annihilation energy, and increase the heat flo…
Co-SIMP Miracle
Juri Smirnov, John F. Beacom
We present a new mechanism for thermally produced dark matter, based on a semi-annihilation-like process, , with intriguing consequences fo…
Vainshtein Screening in Bimetric Cosmology
Marvin Lüben, Angnis Schmidt-May, Juri Smirnov
We demonstrate that the instabilities in linear cosmological perturbations in bimetric theory are the manifestation of the non-linear Vainshtein mechanism on an FRW background. The…
Dark Matter meets Quantum Gravity
Manuel Reichert, Juri Smirnov
We search for an extension of the Standard Model that contains a viable dark matter candidate and that can be embedded into a fundamental, asymptotically safe, quantum field theory…
The Thermal History of Composite Dark Matter
Nicola Andrea Dondi, Francesco Sannino, Juri Smirnov
We study the thermodynamic history of composite Dark Matter models. We start with classifying the models by means of the symmetries partially protecting the composite Dark Matter d…
TeV-Scale Thermal WIMPs: Unitarity and its Consequences
Juri Smirnov, John F. Beacom
We re-examine unitarity bounds on the annihilation cross section of thermal-WIMP dark matter. For high-mass pointlike dark matter, it is generic to form WIMP bound states, which, t…
Safe Clockwork
Francesco Sannino, Juri Smirnov, Zhi-Wei Wang
In this letter we demonstrate that safe quantum field theories can accommodate the clockwork mechanism upgrading it to a fundamental theory a lá Wilson. Additionally the clockwork…
Cosmological Abundance of Colored Relics
Christian Gross, Andrea Mitridate, Michele Redi +2
The relic cosmological abundance of stable or long-lived neutral colored particles gets reduced by about a few orders of magnitude by annihilations that occur after QCD confinement…
Long Range Effects in Gravity Theories with Vainshtein Screening
Moritz Platscher, Juri Smirnov, Sven Meyer +1
In this paper we study long range modifications of gravity in the consistent framework of bigravity, which introduces a second massive spin-2 field and allows to continuously inter…
Colored Dark Matter
Valerio De Luca, Andrea Mitridate, Michele Redi +2
We explore the possibility that Dark Matter is the lightest hadron made of two stable color octet Dirac fermions . The cosmological DM abundance is reproduced for $M_{\ca…
