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 establishes a systematic correspondence between massless and massive contact amplitudes in the SMEFT by utilizing a spin-transversality basis and minimal-helicity-chirality expansion to map unbroken-phase Wilson coefficients to broken-phase amplitude coefficients for processes involving three to eight external particles.
This paper extends recent findings on spatial infinity by explicitly proving that logarithmic supertranslations are also symmetries at null infinity and demonstrating that their associated charges match at the intersection of spatial and null infinity, thereby confirming their inclusion in the asymptotic symmetry group of gravity in asymptotically flat spacetimes.
This paper proposes a method to optimize the dilaton potential in bottom-up holographic QCD by constructing a direct model that reproduces the phase transition features and critical endpoint of a light-quark reconstruction model, thereby successfully capturing the system's first-order phase transition line and confinement properties.
This paper establishes a general framework for deriving non-invertible selection rules in theories with discrete non-Abelian symmetries by analyzing -gauged models via the semidirect product , introducing projected characters to determine allowed couplings and demonstrating that the resulting field components form an associative fusion-like algebra.
This paper proposes a novel, model-bias-free methodology for extracting proton parton distribution functions by reformulating the global analysis of deep inelastic scattering data as a linear tensor reconstruction inverse problem, thereby replacing traditional parameter fitting with the direct solution of coupled linear integral equations derived from perturbative QCD.
This paper theoretically formulates direct waves in extreme-mass-ratio mergers as source-driven signals reflecting orbital motion and ergoregion effects, introducing a pole-splitting method to separate these waves from quasinormal modes and demonstrating that the resulting non-pole sector serves as a probe of black hole frame dragging and redshift.
This paper establishes a complete renormalization-group framework for fermionic dark matter effective interactions, deriving anomalous dimensions and matching conditions to perform a comprehensive phenomenological analysis that yields stringent constraints on Wilson coefficients from diverse precision observables, probing new physics scales up to hundreds of TeV.
This paper provides a comprehensive overview of recent technological advancements regarding the critical point of the chiral phase transition in Quantum Chromodynamics, with a specific focus on the application of Effective Field Theories.
This paper investigates gravitational wave memory in generalised Ellis-Bronnikov wormholes by analyzing the response of timelike geodesics and congruences to localized pulses, revealing that the resulting displacement, velocity, expansion, and shear signatures depend systematically on the wormhole's throat radius, steepness parameter, and the pulse's location relative to the throat.
This paper presents a generalized flavor holographic QCD model that incorporates explicit quark mass dependence to achieve agreement with lattice thermodynamics at high temperatures and to predict a smooth equation of state with significantly lower latent heat for the nuclear-to-quark matter transition at high densities.
