Hep-Th, or high-energy theoretical physics, explores the fundamental building blocks of our universe and the forces that govern them. Researchers in this field use complex mathematics to understand everything from subatomic particles to the behavior of black holes, often pushing the boundaries of what we know about space and time.
At Gist.Science, we monitor the arXiv repository to ensure you stay ahead of the curve in this rapidly evolving discipline. For every new preprint uploaded to arXiv under this category, our team generates both accessible plain-language overviews and detailed technical summaries, making cutting-edge research understandable regardless of your background.
Below are the latest papers in high-energy theoretical physics, curated to help you navigate the most significant recent discoveries.
This review paper synthesizes current theoretical, cosmological, astrophysical, and experimental efforts to explore the theoretically motivated meV axion mass range, highlighting the convergence of diverse approaches aimed at discovering these particles as a key probe for beyond-Standard-Model physics.
This paper investigates photon-photino mixing induced by a Lorentz-symmetry violating fermionic-condensate background within a supersymmetric framework and derives constraints on the strength of this background by analyzing stellar energy loss and solar data.
This paper challenges the conventional view that black holes possess intrinsic entropy by employing a linear amplifier model to argue that black holes instead create and emit entropy during their operation, with the total emitted entropy matching the standard expression proportional to the square of the black hole's mass.
This paper investigates a scale-invariant extension of the Standard Model where the electroweak phase transition is delayed until a low temperature of approximately 28 MeV and triggered by the QCD chiral symmetry-breaking transition, leading to unique cosmological consequences such as the potential formation of primordial black holes, quark-lepton nuggets, and low-frequency gravitational waves.
This paper summarizes the state-of-the-art techniques for analytically calculating non-standard worldline integrals, which combine vast numbers of Feyman diagrams into compact representations, with a specific focus on examples from QED in vacuum and constant external fields.
This paper demonstrates that gravitational-wave-inspired periodic deformations applied to the SYK model induce a frequency-selective suppression and a genuine time delay in holographic wormhole teleportation fidelity, confirming that such channels degrade gracefully under metric perturbations and remain robust across finite system sizes.
This paper investigates the cosmological implications of the "slingshot effect," a phenomenon where sources crossing domain walls generate confined strings, potentially sourcing gravitational waves, dark matter via Kaluza-Klein gravitons, and primordial black holes across observationally relevant mass ranges.
This paper presents a globally consistent Type IIA string theory framework on a orientifold that simultaneously addresses the strong CP problem via a four-form flux mechanism and predicts a multi-component dark matter scenario consisting of axions and neutralinos with computed relic abundances and observational signatures.
This paper advances the M-theoretic Emergence Proposal by demonstrating that the regularization used to derive classical cubic terms from quantum effects in 4D compactifications is equivalent in both complex structure and Kähler moduli spaces, and by extending this framework to account for linear terms in the one-loop prepotential .
This paper reviews fractional Kaehler potentials that, when combined with chaotic inflationary potentials in a non-linear sigma model, establish a class of -inflationary attractors compatible with ACT DR6 data and potentially observable tensor-to-scalar ratios, while also demonstrating their realization within supergravity via shift-symmetric Kähler potentials and monomial superpotentials.
