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 how the intense electromagnetic fields in ultraperipheral heavy-ion collisions induce -lepton polarization that modifies decay distributions, proposing this phenomenon as a novel sensitive probe for CP violation at the LHC and future colliders.
QEDtool is an object-oriented Python package designed to perform numerical quantum electrodynamics calculations by evaluating Feynman amplitudes in the momentum-helicity basis to reconstruct and quantify full state correlations, polarization, and entanglement for arbitrary initial scattering states across different inertial frames.
This paper presents a method to analytically construct a localized, five-dimensional rotating braneworld black hole that connects to an AdS boundary and reproduces the standard four-dimensional Kerr spacetime on the brane, supported by a non-diagonal anisotropic fluid in the bulk without requiring matter on the brane itself.
This paper reassesses the accuracy of the Dudley-Finley approximation for Kerr-Newman quasinormal modes by comparing it to full coupled calculations, revealing typical agreement within 10% for real frequencies and 1% for imaginary parts, while also deriving analytic boundaries for distinct near-extremal damping regimes and analyzing the trajectories of high-overtone modes.
This paper proposes a general parametrization for new physics corrections to gauge couplings, demonstrating that full unification typically occurs near the Standard Model's partial unification scale unless corrections are highly asymmetric, while also revealing a phenomenologically significant possibility for unification at approximately 100 TeV via string-inspired corrections.
This paper computes the bulk-to-bulk photon propagator in Anti-de Sitter space across various gauges using momentum and position space techniques, ensuring gauge invariance through BRST symmetry and identifying the Fried-Yennie gauge as providing the simplest position space expression with improved infrared behavior.
This paper proposes the existence of a new class of ultra-compact astrophysical objects with masses around solar masses, which are stabilized against gravitational collapse by the pressure generated from weak interactions via -boson exchange at ultrahigh densities, effectively realizing Zeldovich's proposed equation of state.
This paper utilizes kinetic theory to demonstrate that expansion-induced momentum anisotropy in the quark-gluon plasma enhances the Seebeck coefficient, thereby strengthening the induced electric field and offering potential signatures for future phenomenological studies of heavy-ion collisions.
This paper investigates a relativistic self-gravitating equilibrium system with slow steady flow by developing a perturbative framework to derive differential equations for structural corrections and proposing a new condition that uniquely determines the unconventional form of the entropy current and its leading-order parameter.
This paper investigates the emergence of a time-crystalline phase in a single-band holographic superconductor by extending the AdS/CFT framework with nonlinear gauge-scalar coupling and external driving, revealing broken time-translation symmetry through multi-scale analysis and numerical quasinormal mode computations.
