Emergent cosmology from matrix theory
Journal of High Energy Physics, 2022 Matrix theory is a proposed non-perturbative definition of superstring theory in which space is emergent. We begin a study of cosmology in the context of matrix theory.

Stop Co-Annihilation in the Minimal Supersymmetric Standard Model Revisited [PDF]
, 2018 We re-examine the stop co-annihilation scenario of the Minimal Supersymmetric Standard Model, wherein a bino-like lightest supersymmetric particle has a thermal relic density set by co-annihilations with a scalar partner of the top quark in the early ...

Neutrino cosmology after DESI: tightest mass upper limits, preference for the normal ordering, and tension with terrestrial observations [PDF]
Journal of Cosmology and Astroparticle PhysicsThe recent DESI Baryon Acoustic Oscillation measurements have led to tight upper limits on the neutrino mass sum, potentially in tension with oscillation constraints requiring ∑ mν ≳ 0.06 eV.

Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2018 The discovery of the Higgs boson in 2012 and other results from the Large Hadron Collider have confirmed the standard model of particle physics as the correct theory of elementary particles and their interactions up to energies of several TeV. Remarkably, the theory may even remain valid all the way to the Planck scale of quantum gravity, and therefore

From Reductionism to Contextualism: L. Wittgenstein and the Dimensions of Modern Cosmology [PDF]
Философия и космологияThis article offers a consideration of potential ways to apply the methodology of the philosophy of everyday language to solve modern problems of cosmology and the philosophy of cosmology. Modern cosmology emerges as an independent scientific discipline,

Long range interactions in cosmology: implications for neutrinos [PDF]
Journal of Cosmology and Astroparticle Physics, 2021 Cosmology is well suited to study the effects of long range interactions due to the large densities in the early Universe. In this article, we explore how the energy density and equation of state of a fermion system diverge from the commonly assumed ...

When misinterpreting the Bible becomes a habit
HTS Teologiese Studies/Theological Studies, 2018 Ancient Near Eastern (ANE) texts should be interpreted against the background of the magico-mythical cosmology of their time, and the Bible is no exception.

Journal of High Energy Physics, 2020 A quantum extremal island suggests that a region of spacetime is encoded in the quantum state of another system, like the encoding of the black hole interior in Hawking radiation.
