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 magnetic deformation of the (2+1)d Ising CFT on a spatial sphere by comparing Fuzzy Sphere simulations with the Truncated Conformal Space Approach to extract universal infinite-volume quantities and provide evidence for a bound state with small binding energy.
This paper introduces a novel numerical method combining the Witten-Feynman parameterization with a "reduced Schwinger" technique to analytically resolve oscillatory subintegrals, thereby enabling the first direct evaluation of complete one-loop cosmological bispectrum signals for general masses and momenta and facilitating their comparison with CMB data.
This paper investigates the collider phenomenology of a topological portal connecting QCD to pseudo-Nambu-Goldstone dark matter by constructing a weakly coupled ultraviolet completion with a vector mediator, which enables the calculation of thermal coannihilation and provides testable predictions for LHC, LEP, bottomonium, and future FCC-ee experiments.
This paper proposes a framework that associates quantum states to arbitrary closed spacetime regions by defining a gravitational Hilbert space via path integrals over complexified geometries, thereby establishing a correspondence between non-asymptotic spacetime regions and quantum states that explains the efficacy of tensor network models while revealing that von Neumann entropy is determined solely by maximin surfaces independent of complex deformations.
This paper clarifies the origin and computation of Sommerfeld enhancement and bound states in singular potentials using non-relativistic effective field theory and position-space regularization, demonstrating that while weakly coupled UV-complete theories yield no enhancement, derivatively coupled pseudoscalar mediators can generate significant enhancement through the interplay of large hierarchies between the cutoff scale and dark matter mass.
This paper demonstrates that a formal deformation quantisation of degree-2 differential graded symplectic manifolds generates the complete classical kinematics and dynamics of NS-NS supergravity and double field theory, providing a unified algebraic framework that extends the tensor hierarchy, incorporates the dilaton via a graded Moyal–Weyl star product, and facilitates the construction of the DFT action.
This paper establishes an obstruction to dimension-independent local color-kinematics duality for the one-loop six-gluon amplitude in pure Yang-Mills theory by demonstrating that no polynomial contact correction can simultaneously satisfy higher-cut solutions and the required fourfold cut, thereby excluding an all-multiplicity polynomial family under these conditions.
This paper proposes a structural infrared mechanism in supersymmetric quantum field theories on de Sitter backgrounds where long-wavelength gravitational fluctuations suppress asymptotic particle states and redistribute spectral weight to continuum sectors, a hypothesis tested through a cosmological realization that yields S8 and fS8 values consistent with benchmark observations without proving the underlying dark-sector assignment.
This paper unifies Costello's extension of the AKSZ construction to non-topological theories and the presymplectic approach into a single general algebraic framework involving constrained DGCAs and degenerate presymplectic structures, which is then used to derive first-principles formulations for the Chalmers-Siegel model and self-dual higher-spin gauge theories.
This paper demonstrates that enforcing -channel unitarity in high-energy elastic $pp$ scattering models significantly increases the extracted dynamical gluon mass scale from approximately 300–420 MeV to 750–1100 MeV, revealing that the physical infrared scale is a unitarity-dressed quantity determined jointly by the nonperturbative gluon propagator and multiple-exchange dynamics.
