On the change of old neutron star masses with galactocentric distance

, 2020
We show that the pulsar mass depends on the environment, and that it decreases going towards the center of the Milky Way. This is due to two combined effects, the capture and accumulation of self-interacting, non-annihilating dark matter by pulsars, and ...

Particle dark matter searches in the anisotropic sky [PDF]

, 2014
Anisotropies in the electromagnetic emission produced by dark matter annihilation or decay in the extragalactic sky are a recent tool in the quest for a particle dark matter evidence.

IceCube at the frontier of macroscopic dark matter direct detection

Journal of High Energy Physics, 2022
For a class of macroscopic dark matter models, inelastic scattering of dark matter off a nucleus can generate electromagnetic signatures with GeV-scale energy.

Dark magnetic dipole property in fermionic absorption by nucleus and electrons

Journal of High Energy Physics, 2022
The fermionic dark matter (DM) absorption by nucleus or electron targets provides a distinctive signal to search for sub-GeV DM. We consider a Dirac fermion DM charged under a dark gauge group and with the dark magnetic dipole operator.

Searching For Dark Matter Subhalos In the Fermi-LAT Second Source Catalog [PDF]

, 2011
The dark matter halo of the Milky Way is expected to contain an abundance of smaller subhalos. These subhalos can be dense and produce potentially observable fluxes of gamma rays.

Multi-component dark sectors: symmetries, asymmetries and conversions

Journal of High Energy Physics, 2022
We study the relic abundance of several stable particles from a generic dark sector, including the possible presence of dark asymmetries. After discussing the different possibilities for stabilising multi-component dark matter, we analyse the final relic

Strong gravitational lensing probes of the particle nature of dark matter

, 2009
There is a vast menagerie of plausible candidates for the constituents of dark matter, both within and beyond extensions of the Standard Model of particle physics. Each of these candidates may have scattering (and other) cross section properties that are consistent with the dark matter abundance, BBN, and the most scales in the matter power spectrum ...

Connecting neutrino physics with dark matter [PDF]

, 2014
The origin of neutrino masses and the nature of dark matter are two of the most pressing open questions of the modern astro-particle physics. We consider here the possibility that these two problems are related, and review some theoretical scenarios ...

Associated production of neutrino and dark fermion at future lepton colliders

Journal of High Energy Physics, 2023
Fermionic dark matter can be pairly produced and hence searched with missing energy at colliders. We extend such probe to the associated production of a neutrino and a dark sector fermion at the future e + e − colliders such as CEPC, FCC-ee, ILC, and ...

Detection Rates for Kaluza-Klein Dark Matter [PDF]

, 2002
We consider the lightest Kaluza-Klein particle at N=1 mode (LKP) of universal extra dimension to be the candidate for Dark Matter and predict the detection rates for such particles for Germenium and NaI detectors.
