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 paper constructs a continuous family of Fierz–Pauli systems for charged massive spin- particles interpolating between supergravity and decoupled-string limits, demonstrating that while both endpoints yield a gyromagnetic ratio of , only the supergravity realization remains consistent with dynamical gravity and non-constant electromagnetic fields due to the vanishing of specific quadratic chiral terms.
This paper resolves the divergence of the semiclassical partition function for spherically-symmetric AdS Einstein-Maxwell black holes by employing a Lorentzian gravitational path integral and Picard-Lefshetz analysis to demonstrate that only a finite subset of complex saddles contributes at finite temperature, while also establishing convergence for the analogous uncharged BTZ black hole case.
This paper proposes a UV-complete and stable Quintom dark energy model derived from a 5D Non-Perturbative Gauge-Higgs Unification framework on an anisotropic orbifold lattice, which naturally explains the DESI DR2 data through a massive gauge ghost mechanism while avoiding fundamental instabilities and fine-tuning issues.
This paper proposes a novel cogenesis framework based on the type-I Dirac seesaw mechanism, where the out-of-equilibrium decays of heavy vector-like fermions simultaneously generate the baryon asymmetry and an asymmetric dark matter component, allowing for successful cogenesis with dark matter masses ranging from 100 MeV to 39 TeV while remaining testable through neutrino, dark matter, CMB, and gravitational wave observations.
This paper investigates the frequency-dependent dynamical tidal response of regular black holes (Bardeen, Hayward, and Fan-Wang) by solving perturbation equations and employing a shell effective field theory framework, revealing that dynamical Love numbers exhibit strong dispersion and resonant features that encode near-horizon and interior structural information inaccessible in the static limit.
By modeling a collapsing matter shell within an effective quantum field theory where Planck length fluctuations are retained until the final limit, the paper demonstrates that finite particle production prevents the scalar expansion parameters from vanishing, thereby suppressing the formation of an apparent horizon and suggesting that astrophysical black holes may be regular, horizonless compact objects.
This paper utilizes a five-dimensional holographic model to demonstrate that a time-dependent vacuum angle can induce a delayed deconfinement-to-confinement phase transition with significant supercooling, thereby altering the characteristics of the resulting gravitational wave signals in early universe cosmology.
This paper demonstrates that in a strong self-dual background, Yang-Mills theory and adjoint QCD abelianize in the infrared with an integer-quantized beta function driven exclusively by exact zero modes, leading to a conjectured non-commutative effective field theory free of UV/IR mixing.
This paper investigates the interplay between magic and entanglement in two-qubit systems by deriving analytical formulas and explicit state parametrizations for the Pareto frontiers of maximal and minimal magic (quantified by Rényi-2 entropy) across all levels of concurrence.
Using the Wald formalism, this paper demonstrates that the identification between bulk and boundary conserved quantities induced by perturbations of generic non-electromagnetic matter fields holds for both asymptotically flat and asymptotically AdS stationary spacetimes, and reduces to the familiar form for test point particles as a limiting case.
