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 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.
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.
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.
This paper computes the one-loop contribution to the semiclassical partition function of static, charged near-extremal black holes in five-dimensional Einstein-Gauss-Bonnet gravity, revealing that tensor, vector, and gauge fluctuations induce universal logarithmic corrections to the entropy with a low-temperature scaling of .
This paper develops a quantum field-theoretic framework that derives a generalized Lindblad master equation to describe neutrino decoherence from momentum-changing scattering in a medium, explicitly linking decoherence parameters to scattering cross sections to probe new physics scenarios including non-standard interactions and dark matter.
This paper derives exact quasinormal modes for massive scalar, fermionic, and vector perturbations around a rotating BTZ-like black hole in Einstein-bumblebee gravity, revealing that the Lorentz symmetry breaking parameter slows field decay by affecting only the imaginary parts of the frequencies while preserving the standard BTZ real parts and confirming the validity of the AdS/CFT correspondence through universal conformal weights.
This paper investigates the scattering of two-dimensional fermion wavepackets by the Maldacena-Ludwig boundary condition, deriving explicit expressions for the resulting exotic fractionally-charged states and demonstrating that while their charge density is localized with a finite fractional integral, the expected number of fermions and anti-fermions diverges as the wavepacket becomes point-like.
