Exploring primordial black holes and gravitational waves with R-symmetric GUT Higgs inflation by Nadir Ijaz, Mansoor Ur Rehman

“…The predicted stochastic gravitational wave background falls within the sensitivity range of existing and upcoming gravitational wave detectors, while primordial black holes hold the potential to explain the abundance of dark matter. Furthermore, we highlight the significance of the leading-order nonrenormalizable term in the superpotential of achieving inflationary observables consistent with the latest experimental data. …”

A holographic perspective on the axion quality problem by Peter Cox, Tony Gherghetta, Minh D. Nguyen

“…Abstract The axion provides a compelling solution to the strong CP problem as well as a candidate for the dark matter of the universe. However, the axion solution relies on the spontaneous breaking of a global U(1)PQ symmetry, which is also explicitly violated by quantum gravity. …”

Strongly interacting dark sectors in the early Universe and at the LHC through a simplified portal by Elias Bernreuther, Felix Kahlhoefer, Michael Krämer, Patrick Tunney

“…We lay out the requirements for the model to be cosmologically viable, identify annihilations into dark vector mesons as the dominant dark matter freeze-out process and discuss bounds from direct detection. …”

Long-lived particle searches with the ILD experiment by Klamka Jan Franciszek, Żarnecki Aleksander Filip, Jeans Daniel

“…We study challenging scenarios involving small mass splittings between heavy LLP and dark matter, resulting in soft displaced tracks. As an opposite case, we explore light pseudoscalar LLPs decaying to boosted, nearly collinear tracks. …”

Dynamical systems of modified Gauss–Bonnet gravity: cosmological implications by Ashutosh Singh

“…We utilize the dynamical system approach to study the cosmic dynamics of two different class of f(R, G) models composed of radiation and matter (cold dark matter and baryonic matter). The linear perturbations around the fixed points are studied to explore the corresponding stability of points. …”

On the analytic generalization of particle deflection in the weak field regime and shadow size in light of EHT constraints for Schwarzschild-like black hole solutions by Reggie C. Pantig

“…This work provided four examples, including Schwarzschild-like solutions in the context of Bumblebee gravity theory and the Kalb–Ramond framework, as well as one example from a black hole surrounded by soliton dark matter. These examples explore distinct mechanisms of Lorentz symmetry breaking, with results that are either new or in agreement with existing literature. …”

Weyl fermion creation by cosmological gravitational wave background at 1-loop by Azadeh Maleknejad, Joachim Kopp

“…Notably, if Weyl fermions eventually acquire mass, and assuming realistic — and potentially detectable — gravitational wave backgrounds, the mechanism can explain the abundance of dark matter in the Universe. More generally, gravitational-wave induced freeze-in is a new purely gravitational mechanism for generating other feebly interacting fermions, e.g. right-handed neutrinos. …”

Metric-affine cosmological models and the inverse problem of the calculus of variations. Part II: Variational bootstrapping of the $$\Lambda $$ Λ CDM model by Ludovic Ducobu, Nicoleta Voicu

“…Starting from an “educated guess” that formally resembles the Einstein field equations with a cosmological “constant” (actually, a scalar function built from the metric and the connection) and a dark matter term, the method then allows to find “corrected” metric equations and to “bootstrap” the connection field equations. …”

Thermodynamic Phase Transition of Anti De Sitter Schwarzschild Scalar-Tensor-Vector-Black Holes by Hossein Ghaffarnejad, Elham Ghasemi

“…Instead ofscalar-tensor gravitymodels which are applicable fordescription of cosmic inflation with unknown dark sector ofmatter/energy, at present tensethere are presented different alternativescalar-tensor-vector gravitieswhere meaningful dynamical vector fields can support cosmicinflation well without to use dark matter/energy concept. One ofthese gravity models was presented by Moffat whichits modified Schwarzschild black hole solution is used tostudy thermodynamic phase transition in presence of the AdS spacepressure in this article. …”

In experimental situations, these measurements are corrupted by noise generated by secondary optical and electronic processes. …”

Extensive composable entropy for the analysis of cosmological data by Constantino Tsallis, Henrik Jeldtoft Jensen

“…An entropy is composable if it satisfies that the entropy SA of a system A=B×C consisting of two statistically independent parts B and C is given in a consistent way as SA=Φ(SB,SC) where the composition function Φ(x,y) is obtained from group-theory.We further show that (α,γ)=(1,2/3) satisfactorily agrees with cosmological data measuring neutrinos, Big Bang nucleosynthesis and the relic abundance of cold dark matter particles, as well as dynamical and geometrical cosmological data sets.…”

Testing General Relativity Using Large-scale Structure Photometric Redshift Surveys and the Cosmic Microwave Background Lensing Effect by Shang Li, Jun-Qing Xia

“…After obtaining the angular power spectra ${C}_{\ell }^{gg}$ (galaxy–galaxy) and ${C}_{\ell }^{g\kappa }$ (galaxy–CMB lensing) from the combination of DES photometric data and Planck lensing, we derive new measurements of the E _G statistic: E _G  = 0.354 ± 0.146, 0.452 ± 0.092, 0.414 ± 0.069, and 0.296 ± 0.069 (68% confidence limit) across four redshift bins z = 0.30, 0.47, 0.63, and 0.80, respectively, which are consistent with the predictions of the standard Lambda cold dark matter model. Finally, we forecast the E _G statistic using future photometric redshift data from the China Space Station Telescope, combined with lensing measurements from the CMB-S4 project, indicating an achievable constraint on E _G of approximately 1%, improving the precision of tests for GR on cosmological scales.…”
