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 proposes a novel cosmological model where the Big Bang singularity is replaced by a smooth boundary in a purely Riemannian four-dimensional space, from which Lorentzian patches emerge via a signature change induced by a clock field, potentially creating a "Euclidean sea" containing expanding universe islands like our own.
This paper investigates the emergence and detection of Hawking radiation in a quenched 1D chiral spin chain by mapping its dynamics to a curved spacetime Dirac fermion, revealing that while the radiation spectrum exhibits greybody-like deviations, a weakly coupled qubit detector can faithfully measure the Hawking temperature, whereas strong coupling obscures the thermal signature by thermalizing with the global environment.
This paper unifies the correspondence between the one-dimensional free particle and the harmonic oscillator by treating time as a projective coordinate on , thereby revealing how Cayley transformations and the Schwarzian derivative provide a common geometric framework for relating their Schrödinger equations and quantum states via canonical and metaplectic transformations.
This paper investigates self-resonance preheating in deformed -attractor T-models with a Gaussian potential feature, revealing that while the initial energy transfer remains largely unaffected, the feature significantly alters post-resonance dynamics by producing a larger number of smaller, shorter-lived oscillons and modifying the high-frequency gravitational wave spectrum.
This paper reviews recent STAR experiment results on net-proton multiplicity fluctuations from RHIC BES-II collisions to search for the QCD critical point by comparing fourth-order cumulant and factorial cumulant ratios with non-critical theoretical models while addressing initial volume fluctuations and outlining future research directions.
This paper investigates the geodesic motion and epicyclic oscillations of particles around Einstein-Skyrme Anti-de Sitter black holes, revealing a unique signature where the radial frequency overtakes the orbital frequency at large distances, and demonstrates through MCMC analysis of X-ray binary and galactic center QPO data that this model consistently fits observations with a Skyrme charge parameter of approximately 0.6.
This paper proposes that the enhanced Higgs quartic coupling required for radiative electroweak symmetry breaking naturally emerges from SO(10) grand unification, where portal couplings to heavy GUT scalars generate the necessary enhancement factor to align the Standard Model's UV Landau pole with the GUT scale, thereby providing a dynamical origin for both symmetry breaking and the electroweak-GUT hierarchy.
This paper investigates equatorial periodic orbits and their gravitational wave signatures in Euler-Heisenberg black holes surrounded by perfect fluid dark matter, revealing how quantum electrodynamic corrections and dark matter jointly modify orbital stability and produce distinct burst-like waveform features that serve as sensitive probes for strong-field gravity.
This paper investigates how higher-group and non-invertible symmetries in axion effective field theories impose parametric constraints on the emergence of infrared symmetries, revealing that these constraints are universally saturated by anomaly inflow onto topological defects but become redundant in perturbative ultraviolet completions due to scale separation.
This paper presents a novel formulation of four-dimensional linearised gravity as a Lorentz-covariant edge mode of a five-dimensional topological field theory, thereby achieving a democratic treatment of electric-magnetic duality by leveraging the field's realization as a singleton representation of the conformal algebra .
