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 the conformal anomaly in a vector field model by introducing an auxiliary scalar compensator to preserve gauge symmetry and unitarity within dimensional regularization, revealing that this scalar acquires independent dynamics and exhibits unique properties in the four-dimensional limit.
This paper presents the first fully nonlinear numerical relativity simulations of charged black hole mergers, demonstrating that electromagnetic duality induces a degeneracy in gravitational dynamics while rotating the polarization of emitted electromagnetic radiation by the duality angle.
This paper presents the first rigorous determination of the physical masses of electroweak vortex rings in the Standard Model, establishing values of 18.01 and 26.80 TeV for different winding numbers and revealing a self-stabilizing pinch mechanism driven by repulsive interactions and complex current distributions.
This paper predicts that sequential hadronization, where mesons form later than mesons, reproduces the observed elliptic-flow splitting in O--O collisions at TeV and establishes this splitting as a universal chronometer for the quark-gluon plasma's hadronization timeline.
The paper proposes an exact, finite kinematic sector of holography defined on a CFT over an open solid torus in the Weyl frame, which establishes bulk-boundary pairs without requiring standard approximations like large- or strong coupling and provides a replica-free definition of entanglement entropy.
This paper demonstrates that standalone relativistic hydrodynamic effective field theories are inherently acausal and necessitates the inclusion of transient ultraviolet modes to restore causality while preserving the correct late-time hydrodynamic behavior.
This paper demonstrates that right-handed neutrino loops, interacting with the inflaton via a dimension-5 operator that induces an effective chemical potential, can significantly enhance cosmological collider signatures by softening heavy-mass suppression and amplifying oscillatory non-Gaussianities in the primordial three-point correlator.
This paper systematically studies generalized Cartan matrices derived from Calabi-Yau space graphs in Toric Geometry, aiming to characterize generalizations of affine exceptional Kac-Moody algebras.
This paper demonstrates that within Jordan-Brans-Dicke theory, the Emergent Universe scenario can achieve robust stability against both classical perturbations and semiclassical quantum tunneling decay for specific choices of the potential and model parameters, thereby potentially avoiding the instability previously identified by Mithani and Vilenkin.
This paper proposes a new generalization of U(n) Yang-Mills theory by treating the connection and Hermitian form as independent variables, thereby introducing non-trivially interacting fields that form a non-Abelian Stückelberg-like structure which can acquire mass through spontaneous symmetry breaking and reduce to standard Yang-Mills theory in the infinite mass limit.
