On the gravitational stability of a compressed slab of gas in the background of weakly interacting massive particles [PDF]

open access: yes, 1999
Linear stability of an isothermal, pressure-bounded, self-gravitating gas slab which is gravitationally coupled with the background weakly interacting massive particles (WIMPs) is investigated.

Combination of searches for invisible decays of the Higgs boson using 139 fb−1 of proton-proton collision data at s=13 TeV collected with the ATLAS experiment

open access: yesPhysics Letters B, 2023
Many extensions of the Standard Model predict the production of dark matter particles at the LHC. Sufficiently light dark matter particles may be produced in decays of the Higgs boson that would appear invisible to the detector.

An intermediate framework between WIMP, FIMP, and EWIP dark matter

open access: yes, 2011
WIMP (Weakly Interacting Massive Particle), FIMP (Feebly interacting Massive Particle) and EWIP (Extremely Weakly Interacting Particle) dark matter are different theoretical frameworks that have been postulated to explain the dark matter.

Theoretical WIMP–Nucleus Scattering Rates for Isomeric Nuclei

open access: yesParticles
The direct detection of dark matter constituents, particularly weakly interacting massive particles (WIMPs), is central to particle physics and cosmology.

Spin-dependent cross sections of weakly interacting massive particles on nuclei [PDF]

open access: yesPhysical Review D, 1989
We use measured nuclear magnetic moments together with some very general assumptions about nuclear wave functions to estimate the spin-dependent elastic cross sections of supersymmetric dark-matter particles on a variety of nuclei. Our cross sections are nearly always smaller than the corresponding single-particle estimates. In light nuclei with mirror

Dark matter: Red or blue?

open access: yesPhysics Letters B
We report the first calculation of light scattering on heavy dark matter (DM) particles. We show that despite the fact that DM has no direct coupling to photons, the light-DM(γχ) (mχ∼1 TeV) cross-section is non-vanishing, albeit small. The cross section,

Limits on interactions between weakly interacting massive particles and nucleons obtained with NaI(Tl) crystal detectors [PDF]

open access: yesJournal of High Energy Physics, 2007
Limits on the cross section for weakly interacting massive particles (WIMPs) elastic scattering on nuclei in NaI(Tl) detectors at the Yangyang Underground Laboratory are obtained from a 2967.4 kg·day data exposure.

Energy deposition by weakly interacting massive particles: a comprehensive study [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2012
We present results obtained with the updated version of our code MEDEA2, which includes all physical processes necessary to study the energy deposition in the surrounding environment from primary photons and fast leptons produced by dark matter (DM) particle decay/ annihilation.

Weakly interacting, massive particles in horizontal-branch stars

open access: yesThe Astrophysical Journal, 1988
Considerations sur le role des cosmions (ou WIMPs, c.a.d. particules massives en interaction faible) dans les etoiles de la branche horizontale. On montre que ces cosmions s'evaporent facilement de ces etoiles et qu'elles ne jouent pas un role important dans le transport d'energie.

Master Equation for the Motion of a Polarizable Particle in a Multimode Cavity

open access: yes, 2010
We derive a master equation for the motion of a polarizable particle weakly interacting with one or several strongly pumped cavity modes. We focus here on massive particles with complex internal structure such as large molecules and clusters, for which ...
