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 investigates five-dimensional thick brane models in modified teleparallel gravity, demonstrating that the torsional Gauss-Bonnet term significantly alters brane structure through splitting and deformation while enabling the localization of chiral fermion zero modes and the emergence of resonant Kaluza-Klein states.
This paper extends the analysis of CPT-odd electromagnetic responses in Weyl semimetals to the overtilted type-II regime, demonstrating that while the axion-like response remains finite across the type-I to type-II transition, it acquires tilt-dependent renormalizations and cutoff-sensitive terms, ultimately yielding a finite, strongly anisotropic anomalous Hall conductivity in WTe driven by comparable and partially canceling Fermi-sea and Fermi-surface contributions.
This paper establishes a locality condition on the quantum state of hard modes as a unified criterion that ensures the validity of the gradient expansion for inflationary soft modes, suppresses hard-mode loop corrections, guarantees infrared regularity, and underpins generalized soft theorems.
This paper demonstrates that the requirement for a quantum system to remain describable by classical hydrodynamics at low temperatures necessitates a finite classical region within the light cone, which in turn forces the effective relaxation rate to be at least Planckian, thereby deriving Planckian scaling of transport coefficients as a consequence of hydrodynamic self-consistency rather than microscopic quantum constraints.
This paper proves the Gang-Kim-Yoon integrality conjecture for all torus knots and non-negative integers by introducing Verlinde numbers derived from the modular S-matrix, establishing their recursion formulas, and demonstrating how adjoint Reidemeister torsions can be recovered from the Hessian of a birational model of the character variety.
This paper numerically analyzes the large-charge asymptotics of 5D indices, stable pair, and Donaldson-Thomas invariants for hypergeometric Calabi-Yau threefolds using high-genus Gopakumar-Vafa data, revealing precise agreements with black hole and black ring entropies, identifying novel phase transitions in the invariants, and confirming a conjecture by Mariño regarding topological free energies.
This paper demonstrates that in quasi-topological gravity, neutron stars can achieve compactness exceeding the black-hole limit and exhibit enhanced radial stability at high central densities, establishing them as theoretically viable ultra-compact configurations.
Using quantum field theory of linearized gravity, the paper demonstrates that the Berry curvature of right- and left-handed gravitons induces a spin Hall effect in curved spacetime, resulting in a helicity-dependent energy current splitting that is exactly twice the magnitude of the corresponding effect for photons.
This paper proposes the rare Standard Model Higgs decay as a probe of Higgs interactions, calculating its branching ratio of approximately and demonstrating that it can be observed with high significance at both the High-Luminosity LHC and the ILC using multivariate analysis techniques.
This paper presents a recursive perturbative expansion of the Kerr black hole metric in harmonic gauge as a double series in Newton's constant and the spin parameter, detailing the challenges of re-summing the series into a closed form and addressing related dimensional regularization issues.
