高能物理·唯象学：2025–2026 年度综述

An annual survey of the hep-ph arXiv category, covering research published from September 2025 – August 2026. Built on a close-reading set of 132 papers and organised into 37 chapters, it maps the year by the field's research sub-directions.

Book framework (share of the year's output):

• QCD Phenomenology and Hadron Structure (59.7%) — Focuses on strong interaction dynamics, including QCD corrections, hadron structure, and experimental constraints from scattering and cosmological data.
• Collider Physics and Heavy Flavor Production (8.8%) — Investigates particle production mechanisms, heavy quark and meson dynamics, and precision measurements at the LHC and future colliders.
• Flavor Physics and Weak Decays (8.2%) — Explores rare decays, flavor violation, and precision tests of the Standard Model through baryon and lepton decay channels.
• Dark Matter and Axion Phenomenology (5.9%) — Examines detection strategies and theoretical models for dark matter candidates, particularly axions and light scalar particles, across astrophysical and collider contexts.
• Gravitational Waves and Primordial Black Holes (4.4%) — Analyzes gravitational wave signatures from early universe phase transitions, inflation, and primordial black holes, along with detector sensitivity studies.
• Neutrino Oscillations and Non-Standard Interactions (4.2%) — Studies neutrino mass mechanisms, oscillation parameters, and non-standard interactions using atmospheric, solar, and reactor neutrino data.
• Heavy-Ion Collisions and QCD Matter (2.5%) — Investigates the properties of hot and dense QCD matter, including jet quenching, spin polarization, and collective effects in heavy-ion collisions.
• QCD Theory and Lattice Gauge Dynamics (1.8%) — Addresses fundamental QCD aspects such as axion theory, parton showers, lattice gauge theory simulations, and effective field theory applications.
• Nucleon Form Factors and Electromagnetic Structure (1.1%) — Focuses on the determination of nucleon electromagnetic and axial form factors, transition amplitudes, and their role in precision scattering experiments.
• Leptogenesis and Beyond Standard Model Mechanisms (0.8%) — Explores theoretical frameworks for matter-antimatter asymmetry, including seesaw mechanisms, leptogenesis, and bound state spectroscopy.
• Quantum Information and Gravity Interfaces (0.8%) — Applies quantum information concepts, such as entanglement and entropy, to strong-field QED, quantum gravity models, and collider simulations.

Each sub-direction is covered across three chapters — how it framed its questions, the strength of its key findings, and its open debates and frontiers — so the reader gets a traceable picture of what this part of the field actually produced over the year.
