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.

The study of K∗0K^{*0} meson production using a multi-phase transport model at RHIC BES energies

This study utilizes the AMPT model to analyze K∗0K^{*0} meson production in Au+Au collisions at RHIC BES energies, revealing that while the model reproduces experimental K∗0/KK^{*0}/K ratios even without hadronic rescattering, the meson's directed flow and average transverse momentum serve as sensitive probes of the late-stage hadronic medium's lifetime and interactions.

Characterizing bulk properties of gapped phases by smeared boundary conformal field theories: Role of duality in unusual ordering

This paper proposes a framework using smeared boundary conformal field theories to characterize gapped phases and massive renormalization group flows dual to massless ones, revealing that such phases often involve unphysical smeared Ishibashi states and spontaneously break non-invertible symmetries, thereby providing a quantum field-theoretic description of unusual order-disorder coexistence.

Flavor as an Incomplete Structure: Conceptual Questions and the Role of DUNE

This paper argues that while flavor remains a conceptually incomplete aspect of the Standard Model, the DUNE experiment offers a powerful, systematic framework to test the limits of the current three-flavor description and search for small deviations through its unique combination of precision oscillation measurements, near-detector capabilities, and the DUNE-PRISM strategy.

Phenomenological implications of the high-precision COHERENT germanium CEν\nuNS data

This paper presents a comprehensive phenomenological analysis of new high-precision COHERENT germanium CEν\nuNS data to extract updated Standard Model and nuclear physics parameters, including the weak mixing angle and germanium neutron radius, while simultaneously constraining neutrino non-standard interactions through a global combined analysis with other experimental datasets.

Symmetry-Breaking Effects on Form Factors and Observables in B→K0∗(1430)μ+μ−B \to K_0^*(1430)\mu^+\mu^- Decay

This paper computes perturbative QCD corrections to the form factors of the B→K0∗(1430)B \to K_0^*(1430) transition using symmetry-breaking relations and light-cone distribution amplitudes, finding that these effects induce only modest ∼3%\sim 3\% shifts in the branching ratio and lepton polarization asymmetries, thereby establishing a precise Standard Model baseline where significant experimental deviations would signal New Physics.

Pretrained Event Classification Model for High Energy Physics Analysis

This paper introduces a Graph Neural Network-based foundation model pretrained on 120 million simulated high-energy physics events that, when fine-tuned, significantly improves event classification accuracy and efficiency across diverse tasks and simulation frameworks while revealing that performance gains stem from developing new message-passing pathways while preserving general-purpose encoders.
