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 holographic entanglement entropy in a moving charged plasma, revealing that while high velocity and chemical potential initially enhance entropy, thermal fluctuations dominate at extreme temperatures and velocities, whereas in the ultrarelativistic regime, velocity becomes the overwhelmingly dominant factor suppressing both thermal and chemical contributions.
This paper extends renormalization-group-optimized perturbative QCD to -equilibrated matter to derive a compact equation of state for massive quarks, demonstrating that specific renormalization scale parameters can yield stable pure and hybrid quark stars compatible with recent astrophysical observations like PSR J0740+6620 and GW190814.
This paper develops a formalism for Lagrangian gauge theories with asymptotic boundaries by demonstrating how divergent bulk presymplectic structures yield a pair of compatible boundary -cocycles—a renormalized structure and an anomaly cocycle—thereby recovering known holographic Weyl anomalies in AdS and extending them to null infinity in flat space.
This paper introduces a novel algorithm that determines Landau singularities of multi-loop Feynman integrals by analyzing drops in the Euler characteristic over finite fields, successfully identifying complex singularities in previously intractable non-planar and multi-scale diagrams.
This paper derives parity-even transverse-traceless metric-like cubic vertices for massless bosonic higher-spin fields in AdS by extending flat-space results through gauge invariance and dimension-dependent identities, confirming their consistency with minimal coupling to gravity.
The paper argues that naturalness is not an objective measure of physical plausibility but an informational invariant reflecting the structural distinguishability of parameter-to-observable maps, thereby reinterpreting fine-tuning as a representation-dependent feature rather than a fundamental constraint on reality.
This paper investigates how the finite size of "puffy" dark matter influences the Sommerfeld enhancement factor, demonstrating through partial-wave analysis and nugget-type models that particle size is a fundamental determinant of resonance structures alongside low velocity.
This paper establishes that in non-inertial quantum systems, the Krylov complexity corresponds exactly to the mean number of correlated Rindler pairs generated via Bogoliubov mixing, revealing three distinct dynamical regimes including a detuning-dominated localization where complexity remains confined to low Krylov levels.
This paper demonstrates that the Weak Gravity Conjecture arises from boundary Conformal Field Theory calculations for charged black holes in dRGT massive gravity and Einstein-ModMax non-linear electrodynamics, deriving specific charge-to-mass bounds that either universally saturate or depend on non-linearity parameters, while also analyzing how relaxing assumptions like exact extremality and minimal coupling reintroduces model-specific dependencies into these bounds.
This paper demonstrates that the classical duality between dual massive -form gauge theories is broken at the quantum level on topologically non-trivial backgrounds due to topology-sensitive determinants and counterterms proportional to the Euler characteristic, suggesting potential duality violations even in Minkowski space via gravitational instantons.
