[HTML][HTML] Feebly-interacting particles: FIPs 2022 workshop report

C Antel, M Battaglieri, J Beacham, C Boehm… - The European Physical …, 2023 - Springer
Particle physics today faces the challenge of explaining the mystery of dark matter, the origin
of matter over anti-matter in the Universe, the origin of the neutrino masses, the apparent …

[HTML][HTML] Snowmass2021 theory frontier white paper: Astrophysical and cosmological probes of dark matter

KK Boddy, M Lisanti, SD McDermott, NL Rodd… - Journal of High Energy …, 2022 - Elsevier
While astrophysical and cosmological probes provide a remarkably precise and consistent
picture of the quantity and general properties of dark matter, its fundamental nature remains …

Maximizing direct detection with highly interactive particle relic dark matter

G Elor, R McGehee, A Pierce - Physical Review Letters, 2023 - APS
We estimate the maximum direct detection cross section for sub-GeV dark matter (DM)
scattering off nucleons. For DM masses in the range 10 keV–100 MeV, cross sections …

Bounds on long-lived dark matter mediators from neutron stars

TTQ Nguyen, TMP Tait - Physical Review D, 2023 - APS
Neutron stars close to the Galactic center are expected to swim in a dense background of
dark matter. For models in which the dark matter has efficient interactions with neutrons, they …

Celestial-body focused dark matter annihilation throughout the galaxy

RK Leane, T Linden, P Mukhopadhyay, N Toro - Physical Review D, 2021 - APS
Indirect detection experiments typically measure the flux of annihilating dark matter (DM)
particles propagating freely through galactic halos. We consider a new scenario where …

Floating dark matter in celestial bodies

RK Leane, J Smirnov - Journal of Cosmology and Astroparticle …, 2023 - iopscience.iop.org
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 …

Heating neutron stars with inelastic dark matter and relativistic targets

G Alvarez, A Joglekar, M Phoroutan-Mehr, HB Yu - Physical Review D, 2023 - APS
The dense environment of neutron stars makes them an excellent target for probing dark
matter interactions with the Standard Model. We study neutron star heating from capture of …

Dark matter in extreme astrophysical environments

M Baryakhtar, R Caputo, D Croon, K Perez… - arXiv preprint arXiv …, 2022 - arxiv.org
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 as …

Scattering searches for dark matter in subhalos: neutron stars, cosmic rays, and old rocks

J Bramante, BJ Kavanagh, N Raj - Physical Review Letters, 2022 - APS
In many cosmologies dark matter clusters on subkiloparsec scales and forms compact
subhalos, in which the majority of Galactic dark matter could reside. Null results in direct …

Submicrometer perovskite plasmonic lasers at room temperature

S Cho, Y Yang, M Soljačić, SH Yun - Science Advances, 2021 - science.org
Plasmonic lasers attracted interest for their ability to generate coherent light in mode volume
smaller than the diffraction limit of photonic lasers. While nanoscale devices in one or two …
