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 forecasts that space-based observations of extreme-mass-ratio inspirals by LISA can constrain near-horizon multipolar deformations at unprecedented precision levels, offering the first direct empirical tests to distinguish between classical Kerr black holes and quantum-gravity-inspired fuzzball geometries.
This paper demonstrates that the finite-volume critical Ising chain's one-point function, when analytically continued via Borel resummation, possesses a natural boundary along the negative real axis governed by odd-divisor-squared sums, which also dictate the strengths of its factorially divergent large- asymptotics.
This paper calculates the leading-order long-range gravitational potential arising from the non-minimal coupling in perturbative quantum gravity, demonstrating that the effect emerges at the one-loop level with a characteristic behavior and exhibits distinct spin and polarization dependencies for scalar, spin-1, and spin-1/2 fields.
This paper establishes that emergent electric and magnetic 1-form symmetries in QED's soft sector generate an infinite-dimensional Abelian algebra with a central extension, which unifies asymptotic charges and soft photon theorems while determining specific contact terms in scattering amplitudes.
This paper provides a self-contained overview of applying quantum spacetime and quantum Riemannian geometry to theoretical physics, highlighting recent successes such as vacuum energy calculations and a new theory of generally covariant quantum mechanics for black holes, while also presenting new findings like a phase transition in Euclidean quantum gravity and discussing future directions.
This paper investigates a rotating acoustic black hole in a (2+1)-dimensional Lorentz-violating background, demonstrating that symmetry violation enhances the absorption cross section across all energy scales while accelerating the damping of quasinormal modes by reducing their real frequencies and increasing the magnitude of their imaginary parts.
This paper demonstrates that the previously observed universal negativity of the equilateral bispectrum from massive scalar exchange during inflation is not a generic feature, but rather a consequence of restricted operator structures, as including additional EFT operators, reduced sound speed, or multi-particle exchanges can flip the bispectrum's sign to positive.
This paper demonstrates that lattice quantum electrodynamics functions as a quantum error-correcting code by utilizing quantum reference frames to resolve syndrome degeneracy and construct explicit recovery operations for both pure-gauge and fermionic sectors, thereby revealing the deep information-theoretic significance of gauge symmetry as an encoding structure for noise protection.
This paper employs Worldline Effective Field Theory to compute conservative and radiative corrections to the dynamics of inspiralling non-spinning black hole binaries in a dark matter environment containing axion-like particles and dark photons, determining the specific post-Newtonian orders at which axion-electromagnetic coupling and kinetic mixing influence orbital evolution and gravitational or scalar radiation.
This paper proposes a non-unitary, pseudo-hermitian model of two coupled Higgs doublets in four dimensions that exhibits cyclic renormalization group flows and "Russian Doll" scaling of vacuum expectation values, potentially offering a novel explanation for the three families of Standard Model particles and the hierarchy problem.
