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 demonstrates that within single-field inflation models, large-scale modes constrained by CMB observations decouple from small-scale enhancements required for primordial black hole production, ensuring that 1-loop back-reaction effects remain unobservable and do not disrupt large-scale predictions.
This paper develops a general framework based on form factors to analyze the real-time dynamics of integrable boundary quantum quenches, specifically investigating the time evolution of the pre-quench vacuum in the Lee-Yang model and validating these analytical results with numerical calculations using the truncated conformal space approach.
This article proposes two TeV-scale singlet-doublet dark matter models (Majorana and Dirac) that simultaneously explain the origin of radiative neutrino masses, the baryon asymmetry of the universe via leptogenesis, and the dark matter relic density, while offering testable signatures for collider experiments and cosmology.
This paper introduces a simple ansatz utilizing a rotated Pauli basis and a specific phase dependence to derive three distinct families of exact wave solutions for sourceless SU(2) Yang-Mills equations in (3+1) dimensions, ranging from linear Abelian waves and genuinely nonlinear self-interacting waves with constant field offsets to pure gauge solutions.
This paper constructs a traversable wormhole in the near-extremal Kerr background by applying a fermionic double-trace deformation, demonstrating that the absence of fermionic superradiance allows for stable wormhole opening across all regions while producing observable echoes with time delays bounded by the black hole's scrambling time.
This paper develops a systematic procedure to extract gravitational multipole moments from scattering amplitudes in arbitrary dimensions, revealing that while four-dimensional minimally coupled theories can reproduce Kerr-like multipoles, higher-dimensional cases exhibit a breakdown of spin universality where minimally coupled fields fail to reproduce the multipolar structure of the Myers-Perry solution due to the emergence of distinct "stress" moments.
This paper demonstrates that the time-dependent $SU(2)$ Gross-Neveu model is integrable when its coupling strength follows the static model's renormalization group flow, establishing a direct equivalence between time evolution and RG flow that leads to time-dependent dynamical dimensional transmutation and asymptotic freedom toward the WZNW model.
This paper demonstrates that subleading Chern-Simons soft factors in gauge theories remain insensitive to perturbative de Sitter curvature corrections at order , thereby confirming their topological nature and universal behavior in the scattering matrix defined within the static patch.
This paper demonstrates that modeling dust collapse within Asymptotically Safe gravity, where the gravitational coupling vanishes at high energies due to a specific matter-geometry coupling function, leads to the formation of regular black holes that are entirely free of singularities.
This study presents the first general relativistic simulations of accretion-induced collapse using hybrid equations of state, demonstrating that a first-order quark deconfinement phase transition triggers a second collapse and a distinctive neutrino burst, with a tightly constrained onset mass that makes AIC a uniquely sensitive probe for determining QCD phase transition thresholds and the existence of protohybrid stars.
