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.

Improved results of chiral limit study with the large NcN_c standard U(3) ChPT inputs in the on-shell renormalized quark-meson model

This paper demonstrates that incorporating large-NcN_c standard U(3) Chiral Perturbation Theory inputs into the on-shell renormalized quark-meson model yields a more robust framework for chiral limit studies, as evidenced by the RQM-S model's stable saturation patterns compared to the divergent behavior observed in the infrared-regularized RQM-I model.

Constraints on dark axion portal: missing energy and fermion EDMs

This paper investigates the dark axion portal model by analyzing missing energy signatures in electron fixed-target experiments like NA64e and LDMX, deriving new constraints on dark photon and ALP production mechanisms, and establishing limits on CP-violating couplings using current fermion electric dipole moment measurements.

Triple Differential Heavy-to-light Semi-leptonic Decays at Next-to-Next-to-Next-to-Leading Order in QCD

This paper presents the first complete next-to-next-to-next-to-leading order QCD calculation of heavy-to-light semi-leptonic decay structure functions, enabling precision predictions for triple differential rates that are crucial for determining CKM matrix elements and resolving tensions in ∣Vub∣|V_{ub}| measurements.

Heavy-to-light Structure Functions at O(αs3)\mathcal{O}(α_s^3) in QCD

This paper presents the first complete O(αs3)\mathcal{O}(\alpha_s^3) perturbative QCD corrections to heavy-to-light structure functions using a hybrid computational strategy, providing state-of-the-art predictions for semi-leptonic BB-meson decays and revealing novel boundary-effect terms essential for consistent mass-scheme reformulations at third order.
