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.
Using a manifestly real Lagrangian and Pauli-Villars regularization, this paper demonstrates that all parity-odd terms in the Weyl anomaly for chiral fermions cancel out in the integrand, resulting in a purely parity-even anomaly.
The paper introduces "disperon QED," a novel method leveraging dispersion relations, automated tools like OpenLoops, effective field theory, and threshold subtraction to efficiently handle data input for hadronic vacuum polarization insertions in two-loop Monte Carlo calculations, specifically demonstrated through the process in McMule.
This paper investigates constraints on a "chargephobic" dark photon—a light vector boson with suppressed couplings to charged leptons and protons but significant interactions with neutrinos and neutrons—demonstrating that while terrestrial experiments offer weak limits, astrophysical and cosmological observations provide the strongest model-independent bounds across its parameter space.
This paper investigates parton distribution functions at small using an upgraded parton model that incorporates splitting cascades and fusion, revealing a power-law behavior in the moderately small region and predicting parton density saturation at very small .
The authors defend the conclusions of their original article (arXiv:2412.12282) against criticisms raised in a subsequent comment (arXiv:2502.15817v2) regarding QCD factorization with multihadron fragmentation functions.
This report synthesizes the outcomes of the 2025 EIC-France Workshop, outlining theoretical advancements and strategic priorities for the French hadron-physics community, with a specific focus on immediate opportunities in inclusive diffraction and quarkonium production alongside longer-term goals in pion structure and exclusive three-body final states.
This paper demonstrates that when anomalous and non-anomalous global symmetries are simultaneously broken, the resulting Nambu-Goldstone boson is associated with the non-anomalous symmetry, implying that the Majoron originates from rather than to resolve the domain wall problem and that axion-like couplings to gauge fields do not exclusively signal an anomalous origin.
The authors demonstrate that a specific second-order -spin sum rule relating CKM-free hadronic weak charm decay rates holds within the Standard Model, is well-supported by existing data, and can be used to predict unmeasured decay rates.
This paper introduces the first application of Bayes Linear Emulation and History Matching to calibrate non-perturbative models in Monte Carlo event generators, offering a robust method to identify all data-consistent parameter regions rather than relying on traditional best-fit estimates, as demonstrated with hadronisation models in Sherpa.
This paper proposes a renormalizable supersymmetric B-L Higgs inflation model within supergravity that utilizes a fractional shift-symmetric Kähler potential to align with ACT data, simultaneously explaining the MSSM -term and achieving baryogenesis through non-thermal leptogenesis.
