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 synthesizes recent advancements in black hole thermodynamics by utilizing topological numbers to categorize diverse black hole systems into universality classes, thereby analyzing critical points, phase transitions, and their implications for quantum gravity.
This paper investigates the asymptotic causal structure of gravitational effective field theories in black-hole backgrounds, demonstrating that while genuine asymptotic superluminality can occur in spacetime dimensions greater than four, the four-dimensional case remains causally identical to the Schwarzschild solution regardless of higher-derivative corrections, necessitating alternative definitions of superluminality such as asymptotically AdS backgrounds or finite-distance cut-offs.
This paper analyzes charged particle multiplicity distributions in proton-proton collisions to identify a reciprocal symmetry () in KNO scaling violations observed by ATLAS and CMS, utilizing a derived local constraint at the mean multiplicity to extract entanglement entropy while avoiding uncertainties from the distribution tail.
Using a holographic AdS/QCD model, this paper demonstrates that introducing an energy scale in anti-de Sitter space alters the topological class of black holes, thereby mapping the confined-deconfined phase transition to a change in topological charge that occurs at a finite critical temperature via the Hawking-Page transition.
This paper proposes that six-dimensional primordial black holes with masses ranging from sub-gram to grams, stabilized by the memory burden effect or near-extremality in a TeV-scale extra dimension framework, can serve as dark matter candidates while offering distinctive signatures for detection at future colliders and atmospheric neutrino experiments.
This paper establishes the multiplicative renormalizability of CPT-odd Lorentz-violating scalar QCD with adjoint matter at the one-loop level by computing ultraviolet divergences in various Green's functions, demonstrating that all divergences can be absorbed into existing counterterms, and deriving the associated renormalization constants and -functions.
This paper investigates reflection symmetry and Atiyah-Patodi-Singer boundary conditions for twisted Dirac operators on a warped cylinder, establishing that reflection compatibility requires a specific holonomy quantization and demonstrating how spectral flow decomposes into equivariant or mod-two invariants depending on whether the holonomy is fixed or varying.
This paper examines the color structure of two-loop gluon amplitudes in Yang-Mills theory using both color trace and structure constant bases to systematize relations between partial amplitudes.
This paper provides numerical confirmation that large-size Hopf-like solitons exist as local energy minima within the full four-dimensional scalar QED theory, thereby strengthening the Faddeev-Noemi conjecture that these structures arise from a twisted toroidal topology inherent to the model.
This paper investigates how imposing the existence of specific General Relativity solutions, such as Schwarzschild or de Sitter black holes with stealth scalar hair, restricts the parameter space of general quadratic and cubic scalar-tensor theories, revealing that while requiring all such solutions eliminates odd-parity deviations from GR, less restrictive scenarios allow for specific deviations, stability constraints, and modified gravitational wave speeds.
