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 an exact analytical calculation of fermionic bubble loop contributions to cosmological collider signals using parallel spectral and Mellin-Barnes methods, revealing that Yukawa interactions with the inflaton yield a vanishing bispectrum due to a field redefinition of tree-level counterparts.
This paper investigates how modular symmetry in magnetized compactifications is violated as a group-like symmetry due to incomplete multiplet representations arising from Scherk-Schwarz phases, yet continues to govern coupling terms through the appearance of modular forms as coupling constants.
This paper presents a quantum mechanical framework for analyzing the Hilbert spaces of BF-Chern-Simons theory with categorical symmetries, demonstrating that line operator actions are realized via convolution kernels and that the resulting eigenvalue formulas unify the Verlinde formula for finite groups and the semiclassical Hopf-link kernel for compact Lie groups through a common topological origin in .
This paper computes the leading-order and first-order radiative corrections to the Casimir energy of a massive, Lorentz-violating scalar field on a three-edge network by employing a systematic renormalization program with position-dependent counterterms and the box subtraction scheme, demonstrating that the resulting energies are consistently negative.
This paper proposes a compositeness framework where fermion generations are elementary fields whose Yukawa hierarchies and mixing patterns arise from chains of spin-0 subconstituents governed by a discrete gauge symmetry, successfully predicting key observables like the neutrino mass, axion mass, and from just two fundamental parameters.
This paper presents the complete set of ultraviolet-renormalized and infrared-subtracted two-loop virtual fermionic contributions to the Drell-Yan process () using an automated methodology, providing a crucial building block for next-to-next-to-leading order electroweak simulations.
This paper introduces non-integral geometry as a generalized distribution theory where a non-symmetric integration measure yields a universal inverse operator with an additional term , which is proven to act as a regularizing contribution that eliminates complex singularities in image reconstruction.
This paper demonstrates that Krylov complexity fully encodes the dynamics of quantum operators by providing a recursive algorithm to derive Lanczos coefficients from its Taylor expansion, thereby establishing it as a complete characterization of operator evolution distinct from spread complexity.
This paper constructs smooth complex gravitational saddles representing the supersymmetric index for black holes in AdS within the STU model, demonstrating that these solutions emerge consistently from both complexified four-dimensional two-center BPS configurations and six-dimensional black strings, thereby satisfying the necessary conditions for global supersymmetry and thermodynamic consistency.
This paper demonstrates that a previously proposed Hamiltonian formalism for soft excitations in a quark-gluon plasma is also effective for describing the scattering of colorless plasmons off hard thermal particles, leading to the development of a generalized Poisson superbracket, higher-order interaction Hamiltonians, and a self-consistent system of kinetic equations for the system's dynamics.
