Nuclear theory sits at the fascinating intersection of particle physics and the forces that hold our universe together. This field explores how protons and neutrons bind inside atomic nuclei, seeking to understand the fundamental interactions that govern matter at its most dense and energetic levels. While the mathematics involved can be incredibly complex, the core questions are deeply human: how does the universe function at its smallest scales, and what happens when we push matter to its limits?

Below are the latest papers in nuclear theory, distilled and ready for you to explore.
This paper employs potential scattering theory with a parity-dependent surface potential to model the +Be fusion process in the Hoyle resonance region, revealing a double-hump potential structure that predicts unobserved resonances and provides an estimated astrophysical S-factor for practical applications.
By extending the IdylliQ model of Quarkyonic matter to include strangeness, this study demonstrates that -quark saturation delays the onset of hyperons to higher densities (--) and suppresses their occupation, thereby mitigating the hyperon puzzle and preserving the stiffness of neutron star equations of state.
This paper demonstrates that longitudinally polarized protons can induce chirality in the final states of intermediate-energy reactions involving non-coplanar momenta, a phenomenon quantified by the analyzing power and explained through the coupling of incident proton helicity to the orbital chirality of single-particle wave functions.
The GlueX experiment at Jefferson Lab reports the first observations of and photoproduction alongside production, revealing forward-peaked angular distributions consistent with Regge-like -channel exchanges and a phenomenological double-exchange model, while finding no narrow resonant structures and observing a suppression of pairs similar to other reactions.
This paper demonstrates that the mass spectra of both mesons and baryons are accurately described by a parameter-free open-string model with a consistent Hagedorn temperature of approximately 0.34 GeV, supporting the view of baryons as quark-diquark systems and offering new insights into quark deconfinement.
This paper demonstrates that charm quarks produced in the early pre-equilibrium glasma stage of high-energy proton-nucleus collisions acquire significant elliptic flow () through interactions with non-Abelian fields, suggesting that pre-hydrodynamic dynamics play a crucial role in the observed heavy-flavor collectivity in small systems.
This paper presents an open-source C++ implementation of a holographic Einstein-Maxwell-Dilaton model with improved numerical stability to quantify uncertainties in various transport coefficients and energy loss parameters across the QCD phase diagram by propagating lattice QCD constraints via Bayesian sampling.
This paper employs a quark combination model within a hadronic coalescence framework to systematically analyze the production of light nuclei and hypernuclei in Au-Au collisions across the RHIC Beam Energy Scan, successfully explaining existing experimental data for species like deuterons and hypertritons while predicting yields for various -hypernuclei and exploring their production correlations as a function of collision energy.
This paper establishes a unified theoretical framework for Hartree-Fock-Bogoliubov resonant states by combining the complex-scaled Jost function method with Autonne-Takagi normalization to rigorously derive a completeness relation, uniquely define resonant wave functions, and explain hole-type quasiparticle resonances as Fano interference phenomena.
This paper develops a Bayesian inference framework to disentangle genuine collective flow from transverse momentum conservation (TMC) backgrounds in small collision systems, revealing that while +Pb data aligns with standard flow measurements, + collisions require this new method to accurately extract flow magnitudes that are otherwise underestimated due to competing TMC effects.
