Hep-Ph explores the fundamental forces that govern how particles interact and behave at the smallest scales imaginable. This field bridges the gap between theoretical predictions and experimental reality, helping scientists understand the building blocks of our universe without getting lost in complex mathematics. Whether investigating the Higgs boson or searching for new physics beyond current models, these studies push the boundaries of human knowledge about matter and energy.
At Gist.Science, we process every new preprint in this category as soon as it appears on arXiv. We strip away the dense jargon to offer both accessible plain-language explanations and detailed technical summaries, ensuring that groundbreaking research is understandable to everyone from students to seasoned experts. Below are the latest papers in this dynamic field, ready for you to explore with clarity and depth.
This paper proposes Regge trajectory relations for the hexaquark within a triquark-antitriquark framework, demonstrating that its complex internal structure necessitates specific , , and trajectory models distinct from simple meson analogs, while providing mass estimates for the resulting excited states.
This paper proposes a regularization method using a gluon mass parameter and an auxiliary color-octet scalar field to resolve strong divergences, particularly small-x and quadratic ultraviolet transverse divergences, in the canonical front-form QCD Hamiltonian eigenstate picture, thereby enabling the derivation of effective Hamiltonians for both heavy and light quark dynamics.
This paper introduces a novel algorithm that determines Landau singularities of multi-loop Feynman integrals by analyzing drops in the Euler characteristic over finite fields, successfully identifying complex singularities in previously intractable non-planar and multi-scale diagrams.
The paper argues that naturalness is not an objective measure of physical plausibility but an informational invariant reflecting the structural distinguishability of parameter-to-observable maps, thereby reinterpreting fine-tuning as a representation-dependent feature rather than a fundamental constraint on reality.
This paper investigates how the finite size of "puffy" dark matter influences the Sommerfeld enhancement factor, demonstrating through partial-wave analysis and nugget-type models that particle size is a fundamental determinant of resonance structures alongside low velocity.
This paper establishes that in non-inertial quantum systems, the Krylov complexity corresponds exactly to the mean number of correlated Rindler pairs generated via Bogoliubov mixing, revealing three distinct dynamical regimes including a detuning-dominated localization where complexity remains confined to low Krylov levels.
This paper demonstrates that the classical duality between dual massive -form gauge theories is broken at the quantum level on topologically non-trivial backgrounds due to topology-sensitive determinants and counterterms proportional to the Euler characteristic, suggesting potential duality violations even in Minkowski space via gravitational instantons.
This paper proposes that a recent ATLAS excess in the triple Higgs mass region, potentially corresponding to predicted Randall-Sundrum KK graviton resonances at 1000 and 1300 GeV, offers a promising pathway to confirm the existence of these extra resonances and constrain the KK graviton coupling parameter using upcoming LHC Run 3 data.
This paper derives a new dynamical criterion for biased domain-wall formation by evaluating the false-vacuum fraction at the freeze-out temperature of correlation volumes, establishing a stricter condition than the conventional static criterion and providing a necessary consistency check for scaling-regime gravitational-wave estimates.
Using the AMPT model for Au+Au collisions at 200 GeV, this study demonstrates that anisotropic hadronic rescattering, driven by Lorentz boost effects on decay angles, significantly suppresses reconstructed yields and induces apparent spin alignment signals ( deviations) in both production-plane and helicity frames, even in the absence of intrinsic polarization.
