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 investigates three late-time gravity models using DESI BAO and other cosmological data to determine if torsional modifications can alleviate the tension, finding that while phantom-like regimes can partially shift the Hubble constant toward local measurements, none of the models are statistically preferred over the standard CDM model.
This paper presents updated, significantly tighter constraints on the tension of both ordinary cosmic strings and cosmic superstrings by analyzing full Planck and ACT DR6 CMB data, while also releasing a modified CAMB pipeline for computing anisotropies from active networks.
This paper utilizes the functional renormalisation group to demonstrate that the Bars-Yankielowicz class of chiral gauge theories exhibits two distinct infrared phases, including a novel large-colour regime characterized by confinement without symmetry breaking.
This paper presents a systematic classification of tree-level ultraviolet completions for dimension-nine SMEFT operators relevant to short-range neutrinoless double beta decay, identifying 440 minimal UV realizations and providing the first comprehensive compilation of 324 minimal completions involving vector resonances.
This paper proposes a mechanism where light sterile neutrinos below the electroweak scale simultaneously explain the universe's baryon asymmetry and dark matter abundance by behaving as Dirac particles at high temperatures and viable warm dark matter at low temperatures, while analyzing general initial conditions and specific ultraviolet completions under cosmological constraints.
This paper presents six global analyses of generalized parton distributions (GPDs) at zero skewness using various modern PDF sets and factorization scales, demonstrating that NNPDF40 at NLO provides the best fit to elastic electron scattering data while revealing moderate sensitivity to PDF inputs and perturbative orders.
This paper utilizes the latest low-energy electron recoil data from the LUX-ZEPLIN experiment to establish novel, stringent constraints on light mediator models, including universal scalar/vector/tensor interactions and anomaly-free leptophilic gauge extensions, by analyzing solar neutrino-electron scattering and demonstrating significant improvements over existing laboratory, cosmological, and astrophysical bounds.
This paper demonstrates that in a scalar theory with a fourth-order derivative term, strong attractive interactions can generate bound states of massive ghosts and normal fields, offering a potential mechanism for ghost confinement that may resolve unitarity violations in quadratic gravity.
This paper investigates tree-level lepton-flavor-violating decays induced by Lorentz violation in the Yukawa sector of the Standard Model Extension, deriving significantly more restrictive experimental bounds on the associated Lorentz-violating parameters than previously reported.
This paper investigates the lineshape near the threshold by incorporating intermediate meson loops and triangle singularities to distinguish between kinematic effects and genuine exotic hidden charm resonances, offering theoretical predictions for identifying states with quantum numbers in the invariant mass spectrum.
