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 presents the maximal analytic extension of a Schwarzschild-like black hole solution in Lorentz gauge theory, demonstrating that while its causal topology mirrors the standard Schwarzschild spacetime, its geometric properties such as horizon scale and surface gravity are uniquely determined by the parameter .
This paper investigates fermion localization in a five-dimensional braneworld within modified teleparallel gravity , demonstrating that non-minimal coupling to torsional invariants, particularly the teleparallel Gauss-Bonnet term, significantly alters effective potentials to enable the localization of a single chiral zero-mode and the emergence of resonant states, while information-theoretic measures confirm that these torsional modifications induce stronger confinement and nontrivial information redistribution.
This paper establishes a correspondence between Rényi mutual information and stabilizer Rényi entropy in electroweak scattering, attributing their shared dependence on the weak mixing angle to Yukawa mass insertions acting as quantum gates that minimize entropy to values consistent with purely axial vector-like couplings.
This paper investigates non-interacting holographic dark energy with the Hubble radius as an infrared cutoff within Einstein-Cartan gravity, demonstrating that a Weyssenhoff spin fluid naturally induces a torsion scalar scaling as , which drives cosmic acceleration, allows the dark energy equation of state to cross the phantom divide, and modifies the cosmic distance duality relation while remaining consistent with recent DESI observations.
This paper investigates how swampland-motivated priors on the slope and field excursion of an exponential quintessential dark energy model, when combined with observational data from Planck, DESI, and supernovae, can shift the inferred value of spatial curvature () compared to standard theory-agnostic analyses.
This paper investigates the universality of the entanglement viscosity to entropy density ratio for spin-3/2 fields within the Rarita-Schwinger-Adler theory, revealing that while both quantities can be negative (yielding a KSS-bound-saturating ratio), a Zubarev density operator approach confirms a positive entropy, thereby clarifying the origin of the negativity and highlighting the theory's conformal field theory features.
This paper establishes a perturbative framework for the Lorentzian Wetterich Renormalization Group flow within perturbative Algebraic Quantum Field Theory on curved spacetimes, deriving beta functions for interacting scalar and Dirac fields, exploring connections to stochastic dynamics, and proving the local well-posedness of the resulting flow equations using the Nash-Moser theorem.
This paper develops a bottom-up open effective field theory for non-Abelian gauge theories within the Schwinger-Keldysh formalism by explicitly retaining slow environmental color variables to construct a local, gauge-covariant Markov embedding that naturally recovers hard thermal loop responses and provides a systematic framework for studying color transport, memory effects, and fluctuation-dissipation in non-Abelian plasmas.
This paper investigates slow-roll inflation within a broad class of scalar-tensor Gauss-Bonnet models by deriving theoretical predictions for spectral observables and their higher-order runnings, establishing consistency equations, and constraining model parameters against the latest Planck observational data.
This paper investigates the out-of-equilibrium evolution of a superfluid in expanding backgrounds relevant to heavy-ion collisions and cosmology, identifying a novel "attractor time" that characterizes the transition to hydrodynamic attractors and revealing a unique nonlinear regime of constant anisotropy in Gubser flow alongside late-time condensate-dominated behavior in FLRW spacetime.
