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.
The paper establishes a new no-go theorem stating that only closed universes () can be simultaneously nonsingular, geodesically complete, and consistent with the averaged null energy condition (ANEC), while also demonstrating that positive spatial curvature can mimic the effects of phantom dark energy in cosmological observations.
This paper establishes the well-posedness of the analytic Cauchy problem for gradient generalized Ricci solitons on abelian bundle gerbes and solves the associated initial data equations on compact Riemann surfaces, while characterizing self-similar solutions through families of gerbe automorphisms covering diffeomorphisms isotopic to the identity.
This paper proposes a new class of holographic dualities between non-supersymmetric defect conformal field theories and a gravity system comprising a novel D5 probe brane terminating on two D7 branes in , which interpolates between the 1/2-BPS D3-D3 system and a previously studied duality while ensuring anomaly cancellation and stability.
The paper proposes that kinetic mixing between QCD and a hidden-sector three-form gauge field generates an effective shift in the angle, thereby inducing CP-violating effects and potentially impacting standard solutions to the strong CP problem.
The paper uses D-brane configurations to study the moduli space of fractional instantons on a twisted four-torus, demonstrating that this space is locally equivalent to the Higgs branch of an supersymmetric theory with a manifest hyper-Kähler structure.
This paper develops a minisuperspace formulation of the classical double copy for anisotropic Lifshitz spacetimes, demonstrating that the relationship between gravity and gauge theory can be captured through a universal radial operator and an effective potential that accounts for anisotropic scaling and higher-curvature corrections.
This paper proves that the potential previously identified for a scalar-field FLRW universe is the most general local potential allowing for non-trivial conformal Killing vectors by demonstrating that all other mathematical solutions to the integrability conditions are either singular or incompatible with the full equations.
This paper investigates the series representations of -fold Mellin-Barnes integrals used to derive off-diagonal asymptotic expansions for operator functions on curved backgrounds, providing a physical interpretation of these series in terms of UV and IR properties.
This paper investigates how nonlinear Born-Infeld-type electrodynamics affects the spacetime geometry of a charged black hole, demonstrating that the parameter significantly modifies observational signatures such as light deflection, shadow size, and accretion disk images through changes in the effective photon geometry.
This paper proposes an economical five-dimensional brane-world model where a single adjoint scalar field and a singlet dynamically realize domain walls that simultaneously localize fermions, gauge fields, and the Higgs field, while providing a geometric solution to the doublet-triplet splitting problem and reproducing Standard Model Yukawa couplings.
