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.

Dynamically assisted Schwinger pair production in differently polarized electric fields with the frequency chirping

This paper investigates how frequency chirps and field polarization influence dynamically assisted electron-positron pair production within the Dirac-Heisenberg-Wigner formalism, revealing that chirps significantly enhance pair yields through interference effects while simultaneously reducing the system's sensitivity to polarization, thereby offering a pathway for optimizing particle generation.

Dark graviton sensing with magnetically levitated superconductors

This paper proposes using magnetically levitated superconductors to detect ultra-light dark gravitons in the dHz to kHz range, finding that while their sensitivity to matter couplings is limited compared to existing experiments, they could serve as highly sensitive laboratory probes for dark-graviton couplings to electromagnetism.

A search for heavy axion-like particles in light-by-light scattering at the FCC-hh

This paper investigates the potential of the future 100 TeV FCC-hh collider to discover or exclude heavy axion-like particles (ALPs) via light-by-light scattering in pp, pPb, and PbPb collisions, demonstrating that the facility offers significant sensitivity to ALP masses up to the TeV scale compared to current LHC bounds.

Relativistic quantum mechanics of massive neutrinos in a rotating frame

This paper investigates the evolution of massive and massless neutrinos in rotating matter by solving the Dirac equation in a corotating frame, deriving a nonzero electroweak vector current analogous to the chiral vortical effect, and analyzing neutrino flavor oscillations to reveal resonance phenomena and generalize noninertial effects in astrophysical contexts.

Light fermionic dark matter window in the scotogenic inverse seesaw model

This paper identifies a viable light fermionic dark matter candidate with a mass between 58 and 63 GeV within the scotogenic inverse seesaw model that simultaneously explains neutrino masses and satisfies all current experimental constraints, while remaining testable by next-generation direct detection experiments and future colliders.

Astrophysical aspects of string compactifications

This paper explores the astrophysical implications of string-inspired multi-scalar-tensor theories by numerically solving the Tolman-Oppenheimer-Volkov equations to demonstrate how a screening mechanism can suppress the coupling of Brans-Dicke dilatons to macroscopic objects like neutron stars.

Soft Symmetry Breaking as a Nonstandard Source of Mass: Phenomenological Insights from the Two-Higgs-Doublet Model

This paper proposes that the soft-breaking parameter $m_{12}^2$ in the Two-Higgs-Doublet Model acts as a distinct, non-electroweak source of mass for new scalars separate from the electroweak VEV, enabling the definition of mass fractions that are currently constrained by diphoton signal strength measurements and direct resonance searches.

A new method for taming tensor sum-integrals

This paper presents a new method for computing massless bosonic three-loop vacuum sum-integrals by generalizing tensor reduction via dimensionality shifts to finite temperature, thereby enabling the final evaluation of the NNLO Debye screening mass in hot QCD.

New 511 keV line data provides strongest sub-GeV dark matter constraints

Using 16 years of INTEGRAL/SPI data to model detailed positron propagation and density variations, this study establishes the strongest constraints to date on sub-GeV dark matter annihilation and decay by analyzing the 511 keV emission profile, excluding cross-sections down to $10^{-32}$ cm $^3$ s $^{-1}$ for MeV-scale masses.

Factorizing two-loop vacuum sum-integrals

This paper derives analytic results for scalar massless bosonic vacuum sum-integrals at two loops by proving their factorization into one-loop structures, thereby enabling the elimination of these complex terms from perturbative expansions in hot QCD.
