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 modification to the Standard Model where the photon's longitudinal component propagates at an extremely slow speed, breaking Lorentz symmetry and causing charged particles to experience severe momentum-recoils that constrain this speed to be less than , effectively turning the preferred reference frame into a material medium that absorbs momentum from matter.
This paper resolves the conceptual puzzles of the Faddeev–Popov procedure and the persistence of BRST symmetry by interpreting ghosts as a principal connection on the bundle of field configurations, where the BRST operator represents the vertical exterior derivative and the connection's horizontal content provides the essential cross-orbit pairing discarded by simple quotienting.
This paper explores how combining dark dimension scenarios with an axiverse modifies cosmology by enabling freeze-in production of dark matter from Kaluza-Klein towers and suppressing observational constraints through energy dilution across numerous axion towers.
This paper proposes a "nine-link texture" model for Yukawa matrices that naturally links the empirical nearness of CKM unitarity triangle angles to simple fractions of with an underlying theory of flavor and spontaneous CP violation, while simultaneously offering a potential resolution to the strong CP problem.
This paper establishes that within the linearized quantum gravity regime of AdS/CFT, the holographic map preserves relative entropy (satisfying the JLMS condition) and, through a modular crossed product construction, rigorously demonstrates that the state-dependent entropy of dual CFT states satisfies the vacuum-subtracted Hubeney-Rangamani-Takayanagi formula for localized semi-classical excitations.
This paper investigates inflation within unimodular loop quantum cosmology by utilizing a geometrically meaningful unimodular time coordinate independent of matter content to derive analytical and numerical solutions for various potentials, demonstrating that -attractor models can produce observationally consistent bounces with potential quantum-gravity imprints.
This paper establishes a geometric theory of information processing in the Horizon-brightened acceleration radiation (HBAR) channel, demonstrating that the radiative change in black-hole horizon area serves as a fundamental entropy budget that bounds accessible classical information, mutual information, and Fisher-information-based speed limits for atoms falling into black holes.
This paper demonstrates that non-commutativity on a fuzzy sphere enhances Bose-Einstein condensation and superfluidity by raising the critical temperature and inducing a linear-in-temperature normal fluid fraction, a behavior reminiscent of Uemura's law in high- superconductors.
This paper derives the non-relativistic limit of Gaussian covariant hydrodynamics to develop renormalization group equations that incorporate spontaneous stochasticity and anomalous dissipation as macroscopic back-reactions to microscopic fluctuations, thereby bridging the gap between fluid dynamics and statistical mechanics while offering new perspectives on turbulence and mathematical regularity.
Using QCD light-cone sum rules, this study calculates the magnetic dipole moments of doubly-bottom molecular pentaquarks in various configurations, revealing that these moments are highly sensitive to the internal spin structure and quark composition, thereby offering a valuable tool for distinguishing between different molecular states in future experiments.
