Macroscopic dark matter constraints for extended mass functions
Zachary S. C. Picker, Andrew Buchanan, Melissa Diamond +1
We compile and recompute a subset of the landscape of constraints for macroscopic dark matter (macros), explicitly including the dependence on the fraction of dark matter in macros…
New Windows on Heavy Dark Matter: Mineral Melt Modelling and X-Ray Readout for Muscovite Mica
Yilda Boukhtouchen, Joseph Bramante, Andrew Buchanan +5
Muscovite mica is a translucent, layered silicate mineral whose basal cleavage, low radiogenic background, gigayear exposures, and demonstrated track retention over geological time…
Very Heavy and Composite Dark Matter: Theory and Experimental Searches
Joseph Bramante
Dark matter much heavier than the weak scale remains a comparatively unexplored frontier. This review surveys theoretical and experimental developments on very heavy dark matter, i…
Deconstructive Composite Dark Matter Detection
Yilda Boukhtouchen, Joseph Bramante, Christopher Cappiello +1
We investigate the detection of composite dark matter that disassembles into a cascade while crossing the Earth. This occurs for loosely bound composite dark matter, where the bind…
High Mass Dark Matter Searches With the High Speed Flux From the Large Magellanic Cloud
Nassim Bozorgnia, Joseph Bramante, Andrew Buchanan
As the hunt for dark matter progresses, recently there have been advances in the search for heavy dark matter with a mass well above a TeV. We show the importance of properly model…
Galactic magnetic fields seeded by ultralight dark photons
Joshua Berger, Amit Bhoonah, Joseph Bramante +3
In this work, we show that ultralight dark photons, which couple to the Standard Model photon through kinetic mixing, can potentially source galactic scale magnetic fields. Althoug…
Secluded Dark Composites and Remnant Binding Fields
Katarina Bleau, Yilda Boukhtouchen, Joseph Bramante +1
Dark matter may freeze-out and undergo composite assembly while decoupled from the Standard Model. In this secluded composite scenario, while individual dark matter particles may b…
Dark Matter Candidates and Searches
Nassim Bozorgnia, Joseph Bramante, James M. Cline +7
Astrophysical observations suggest that most of the matter in the cosmos consists of a new form that has not been observed on Earth. The nature and origin of this mysterious dark m…
Dimming Starlight with Dark Compact Objects
Joseph Bramante, Melissa D. Diamond, J. Leo Kim
We demonstrate a new technique to search for dark compact objects. When dark matter comprising a dark compact object interacts with photons, the compact object can disperse light t…
Loosely Bound Composite Dark Matter
Javier F. Acevedo, Yilda Boukhtouchen, Joseph Bramante +3
We investigate loosely bound composite states made of dark matter, where the binding energy for constituent particles is less than the constituent mass. We focus on models of nucle…
Cosmology of self-replicating universes in black holes formed by dark matter-seeded stellar collapse
Joseph Bramante, Nirmal Raj
We show that dark matter with certain minimal properties can convert the majority of baryons in galaxies to black holes over hundred trillion year timescales. We argue that this ha…
Dissipative Dark Cosmology: From Early Matter Dominance to Delayed Compact Objects
Joseph Bramante, Christopher V. Cappiello, Melissa D. Diamond +3
We demonstrate a novel mechanism for producing dark compact objects and black holes through a dark sector, where all the dark matter can be dissipative. Heavy dark sector particles…
Neutrino and Gamma-Ray Signatures of Inelastic Dark Matter Annihilating outside Neutron Stars
Javier F. Acevedo, Joseph Bramante, Qinrui Liu +1
We present a new inelastic dark matter search: neutron stars in dark matter-rich environments capture inelastic dark matter which, for interstate mass splittings between about $45…
The Effect of Multiple Cooling Channels on the Formation of Dark Compact Objects
Joseph Bramante, Melissa Diamond, J. Leo Kim
A dissipative dark sector can result in the formation of compact objects with masses comparable to stars and planets. In this work, we investigate the formation of such compact obj…
Dark Matter-Induced Baryonic Feedback in Galaxies
Javier F. Acevedo, Haipeng An, Yilda Boukhtouchen +3
We demonstrate that non-gravitational interactions between dark matter and baryonic matter can affect structural properties of galaxies. Detailed galaxy simulations and analytic es…
Limiting Light Dark Matter with Luminous Hadronic Loops
Joe Bramante, Melissa Diamond, Christopher V. Cappiello +1
Dark matter is typically assumed not to couple to the photon at tree level. While annihilation to photons through quark loops is often considered in indirect detection searches, su…
Dark matter in compact stars
Joseph Bramante, Nirmal Raj
White dwarfs and neutron stars are far-reaching and multi-faceted laboratories in the hunt for dark matter. We review detection prospects of wave-like, particulate, macroscopic and…
Light Dark Matter Accumulating in Planets: Nuclear Scattering
Joseph Bramante, Jason Kumar, Gopolang Mohlabeng +2
We present, for the first time, a complete treatment of strongly-interacting dark matter capture in planets, taking Earth as an example. We focus on light dark matter and the heati…
Diffuse X-Ray and Gamma-Ray Limits on Boson Stars that Interact with Nuclei
Javier F. Acevedo, Amit Bhoonah, Joseph Bramante
Light bosonic dark matter can form gravitationally bound states known as boson stars. In this work, we explore a new signature of these objects interacting with the interstellar me…
Dark Matter In Extreme Astrophysical Environments
Masha Baryakhtar, Regina Caputo, Djuna Croon +37
Exploring dark matter via observations of extreme astrophysical environments -- defined here as heavy compact objects such as white dwarfs, neutron stars, and black holes, as well…
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}…
The Forward Physics Facility: Sites, Experiments, and Physics Potential
Luis A. Anchordoqui, Akitaka Ariga, Tomoko Ariga +78
The Forward Physics Facility (FPF) is a proposal to create a cavern with the space and infrastructure to support a suite of far-forward experiments at the Large Hadron Collider dur…
Scattering searches for dark matter in subhalos: neutron stars, cosmic rays, and old rocks
Joseph Bramante, Bradley J. Kavanagh, Nirmal Raj
In many cosmologies dark matter clusters on sub-kiloparsec scales and forms compact subhalos, in which the majority of Galactic dark matter could reside. Null results in direct det…
Accelerating Composite Dark Matter Discovery with Nuclear Recoils and the Migdal Effect
Javier F. Acevedo, Joseph Bramante, Alan Goodman
Large composite dark matter states source a scalar binding field that, when coupled to Standard Model nucleons, provides a potential under which nuclei recoil and accelerate to ene…
