Description
An annual survey of the nucl-th 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):
- Relativistic Heavy-Ion Collisions and Hadron Production (33.9%) — Investigates particle production, flow correlations, and form factors in relativistic heavy-ion collisions and neutrino-nucleus interactions.
- Nuclear Reaction Cross Sections and Scattering Formalisms (19.5%) — Develops formalisms and calculations for nuclear reaction cross sections, scattering amplitudes, and decay probabilities using various theoretical models.
- Chiral Effective Field Theory and QCD Applications (18.8%) — Applies chiral effective field theory and lattice QCD to determine nuclear forces, parton distributions, and properties of dense matter.
- Neutron Star Equation of State and Dense Matter (14.7%) — Constrains the equation of state of dense nuclear matter and neutron star properties using Bayesian inference and astrophysical data.
- Nuclear Structure and Symmetry in Relativistic Frameworks (5.9%) — Explores nuclear structure, symmetry violations, and collective modes within relativistic and effective field theory frameworks.
- Ab Initio Nuclear Structure and Quantum Computing (2.9%) — Performs ab initio many-body calculations for nuclear structure and explores quantum computing applications for nuclear physics.
- Density Functional Theory and Scattering Amplitudes (2.0%) — Utilizes density functional theory and advanced scattering techniques to extract nuclear properties and interaction potentials.
- Quantum Correlations and Pairing Dynamics (0.8%) — Studies quantum correlations, pairing effects, and dynamical evolution in nuclear systems and open quantum systems.
- Nuclear Astrophysics and Radioactive Decay Processes (0.7%) — Analyzes radioactive decay chains, reaction rates, and gamma-ray signatures relevant to nucleosynthesis and astrophysical events.
- Experimental Data Analysis and Theoretical Comparisons (0.5%) — Compares recent experimental measurements with theoretical predictions for fusion, scattering, and particle emission processes.
- Relativistic Hydrodynamics and Initial State Fluctuations (0.4%) — Investigates relativistic hydrodynamic evolution, initial state conditions, and fluctuation effects in heavy-ion collisions.
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.
