TL;DR: In this article, the authors proposed a novel model in the framework of f (Q ) gravity, which is a gravitational modification class arising from the incorporation of non-metricity, and the model has General Relativity as a particular limit, however at a cosmological framework it gives rise to a scenario that does not have ΛCDM as a limit.

TL;DR: In this article, the authors used Big Bang Nucleosynthesis (BBN) data in order to impose constraints on the exponent of Barrow entropy, which is an extended entropy relation arising from the incorporation of quantum-gravitational effects on the black-hole structure, parameterized effectively by the new parameter Δ.

TL;DR: In this article, a search for leptoquarks produced singly and in pairs in proton-proton collisions is presented, where the lepton is considered to be a scalar particle of charge −1/3e coupling to a top quark plus a tau lepton ( t τ ) or a bottom quark including a neutrino ( b ν ), or a vector particle of a charge +2/3 e coupling to t ν or b τ.

TL;DR: In this paper, the authors present the first quantum field theory model of inflation that is renormalizable in the matter sector, with a super-Hubble inflaton mass and sub-Planckian field excursions, which is thus theoretically and empirically consistent with a high energy completion within a theory of quantum gravity.

TL;DR: In this paper, the spin alignment of vector mesons arising from locally polarized quarks and anti-quarks (local spin alignment) in heavy-ion collisions was investigated, and it was shown that ρ 00 ≠ 1 / 3 does not necessarily signal the global polarization of quarks along the orbital angular momentum of the system, but may also originate from their local spin polarization.

TL;DR: In this article, a toy model for the visible Higgs-Yukawa sector of the Standard Model, coupled to a dark sector through a portal coupling, provides a very first example for a model that simultaneously becomes asymptotically safe at non-vanishing portal coupling and features a strongly enhanced predictive power with calculable values for all interactions.
