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 a scotogenic extension of the Standard Model with two inert doublets and three singlet Majorana fermions, identifying viable parameter spaces for radiative neutrino mass generation and dark matter while revealing that approximately 60% of these regions are excluded by recent CMS measurements of the boson mass due to constraints on the oblique parameter .
This paper extends BCFW-like recursion relations to deformed associahedra and D-type cluster polytopes, demonstrating how these geometric triangulations capture tree-level and one-loop scattering amplitudes in multi-scalar cubic theories and offering a pathway to recover effective field theory amplitudes.
This paper demonstrates that tropicalizing scalar quantum field theory yields an exact, non-linear recursion solution for the quantum effective action that enables a polynomial-time algorithm to sample moduli spaces of metric graphs, thereby proving that perturbative QFT computations lie in the polynomial-time complexity class and successfully evaluating the beta function at 50 loops.
By fitting lattice data for nucleon and pion gravitational -form factors to a -meson pole and background term, the study demonstrates that the -meson acts as a dilaton consistent with effective theory predictions, thereby supporting the existence of an infrared fixed point in QCD and providing a physical interpretation of the -term.
This paper proposes a modified thermal Renormalization Group framework, where a constant dimensionless temperature drives the cosmological constant to transition from negative (consistent with string theory at high temperatures) to positive (consistent with observations at low temperatures), thereby resolving the discrepancy between theoretical predictions and the observed accelerating expansion of the Universe.
This paper investigates the cosmological observational signatures of a hypothetical late-time breaking of symmetry, proposing that the resulting high-energy photon and neutrino spectra—dominated by thermal production from frictional bubble wall interactions—could serve as detectable "doomsday" signals reaching observers before the destructive vacuum transition itself.
This paper establishes an exact 1D-2D correspondence for 2D fermions in a rotating trap (generalizing the Lowest Landau Level problem), enabling a simplified 1D quantum mechanical description of the system's density and entanglement entropy while revealing unique noncommutative features such as the absence of logarithmic scaling in the latter.
This paper defines the Wilson spool for three-dimensional gravity with vanishing cosmological constant by constructing the one-loop partition function of a massive, spinning field from a fixed flat-space cosmology holonomy, while suggesting the definition's geometric independence and potential connections to two-dimensional incarnations.
This paper presents two methodical observations in hyperkähler geometry: a simple explicit proof of a necessary and sufficient condition for a Kähler manifold to be hyperkähler, and a clarification of the two-stage Kähler reduction process (with the second stage identified as Hamiltonian reduction) illustrated through toy models reducing to and to the Taub-NUT metric.
This paper proposes a proof-of-principle mechanism for resolving the cosmological constant problem by introducing a momentum-dependent non-linear interaction in a 4D scalar field theory that breaks translational invariance, thereby generating a dynamically lowered UV cutoff for the Universe while preserving the Planck-scale cutoff required for local particle physics experiments.
