Baryon dark matter
웹We propose new searches for n ′, a dark baryon that can mix with the Standard Model neutron.We show that IsoDAR, a proposal to place an intense cyclotron near a large-volume neutrino detector deep underground, can look for n → n ′ → n transitions with much lower backgrounds than surface experiments. This opportune neutron-shining-through-a-wall … 웹2013년 9월 16일 · We refer to this scenario as Baryonic Dark Matter. The stability of the dark matter candidate is a natural consequence of the spontaneous breaking of baryon number …

웹Diverse astrophysical observations suggest the existence of cold dark matter that interacts only gravitationally with radiation and ordinary baryonic matter. Any nonzero coupling between dark matter and baryons would provide a significant step towards understanding the particle nature of dark matter. Measurements of the cosmic microwave background (CMB) provide … 웹Baryonic dark matter. We investigate a simple extension of the Standard Model where the baryon number is a local gauge symmetry and the cold dark matter in the Universe can be …
웹2024년 4월 3일 · Abstract. We study decuplet baryons from meson-baryon interactions in lattice QCD, in particular, Δ and Ω baryons from P-wave I = 3/2 Nπ and I = 0 $\Xi \bar{K}$ interactions, respectively. Interaction potentials are calculated in the HAL QCD method using 3-quark-type source operators at m π ≈ 410 MeV and m K ≈ 635 MeV, where Δ as well as … 웹2024년 4월 21일 · Also, the temperature of the dark matter is colder than the baryon temperature during this period, so an interaction of the baryon with dark matter can cool …
웹They propose a combination of two causes. First, these high-redshift galaxies were strongly baryon dominated, with dark matter playing a smaller part than in the local Universe and, second, ...
