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?

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 extends a newly introduced framework for single-diffractive hard exclusive processes to the specific case of exclusive real-photon electroproduction, offering a more systematic and transparent approach for extracting generalized parton distributions (GPDs) from experimental data.
This paper presents a theoretical model combining the Boltzmann Transport equation with a q-Weibull distribution to successfully describe the nuclear modification factor of charged and identified hadrons across a wide range of collision energies from RHIC to LHC, revealing a linear mass dependence in key fit parameters.
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 highlights that the Majorana Double Charge Exchange nuclear reaction mechanism serves as a powerful probe for neutrinoless double beta decay dynamics, characterized by its unique universality and independence from the specific nuclei involved.
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 investigates elastic proton-proton and pion-proton scattering within the framework of holographic QCD by modeling Pomeron and Reggeon exchanges as Reggeized spin-2 glueball and vector meson propagators, respectively, and demonstrates that the resulting total and differential cross sections, including Coulomb interactions, align well with experimental data across a wide kinematic region.
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.
