    Z′-mediated dark matter freeze-in at stronger coupling by Giorgio Arcadi, David Cabo-Almeida, Oleg Lebedev

    Published 2025-02-01
    “…We study freeze-in production of fermionic dark matter mediated by a Z′ gauge boson. In particular, we explore the regime of Boltzmann-suppressed production, when the Standard Model (SM) thermal bath temperature never exceeds the dark matter mass. …”

    Gravity-mediated scalar Dark Matter in warped extra-dimensions by Miguel G. Folgado, Andrea Donini, Nuria Rius

    Published 2020-01-01
    “…Abstract We revisit the case of scalar Dark Matter interacting just gravitationally with the Standard Model (SM) particles in an extra-dimensional Randall-Sundrum scenario. …”

    Dark matter annihilation via Breit-Wigner enhancement with heavier mediator by Yu Cheng, Shao-Feng Ge, Jie Sheng, Tsutomu T. Yanagida

    Published 2025-02-01
    “…With the mediator mass larger than the total initial dark matter mass, this annihilation is almost forbidden at late times. …”

    Phenomenology of keV scale sterile neutrino dark matter with S4 flavor symmetry by Nayana Gautam, Mrinal Kumar Das

    Published 2020-01-01
    “…In this framework, we conduct a detailed numerical analysis both for normal hierarchy as well as inverted hierarchy to obtain dark matter mass and DM-active mixing which are the key factors for considering sterile neutrino as a viable dark matter candidate. …”

    Probing late-time annihilations of oscillating asymmetric dark matter via rotation curves of galaxies by Júlia G. Mamprim, Guillermo Gambini, Luan B. Arbeletche, Marcos Olegario, Vitor de Souza

    Published 2025-02-01
    “…Abstract In this paper, we explore the Oscillating Asymmetric Dark Matter (OADM) model to address the core-cusp problem, aiming to resolve the discrepancy between the predictions of the $$\Lambda \textrm{CDM}$$ Λ CDM cosmological model and the observed dark matter profiles in dwarf spheroidal galaxies. …”

    The stability of anisotropic compact stars influenced by dark matter under teleparallel gravity: an extended gravitational deformation approach by Sneha Pradhan, Piyali Bhar, Sanjay Mandal, P. K. Sahoo, Kazuharu Bamba

    Published 2025-02-01
    “…Further, we introduce the concept of space-time deformation caused by dark matter (DM) content in DM haloes, leading to perturbations in the metric potentials $$g_{tt}$$ g tt and $$g_{rr}$$ g rr components. …”

    Star shearing season: transient signals in wave-like dark matter experiments from black hole formation by Arturo de Giorgi, Joerg Jaeckel

    Published 2025-02-01
    “…For small masses this field transient remains rather compact and can induce a transient signal in experiments, in particular those that look for wave-like dark matter. This signal can be correlated with the corresponding astrophysical signal of the event. …”

    Optical features and thermal properties of charged AdS Euler–Heisenberg black hole surrounded by perfect fluid dark matter by M. R. Shahzad, G. Abbas, Tao Zhu, R. H. Ali, Asifa Ashraf, Badr S. Al-Kahtani

    Published 2025-02-01
    “…Abstract In this article, motivated by the high interest in Euler–Heisenberg nonlinear electrodynamic theory, we investigated several thermal aspects of the charged Euler–Heisenberg black hole surrounded by perfect fluid dark matter. To ensure the validity of the first law of thermodynamics, we measured the conserved thermal quantities. …”

    Hidden monopole dark matter via axion portal and its implications for direct detection searches, beam-dump experiments, and the H0 tension by Ryuji Daido, Shu-Yu Ho, Fuminobu Takahashi

    Published 2020-01-01
    “…Abstract Hidden monopole is a plausible dark matter candidate due to its stability, but its direct experimental search is extremely difficult due to feeble interactions with the standard model particles in the minimal form. …”
