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?
At Gist.Science, we make these cutting-edge discoveries accessible by processing every new preprint published in this category on arXiv.

Below are the latest papers in nuclear theory, distilled and ready for you to explore.
This paper presents a general framework for subtracting nonflow effects from multi-particle cumulants in small collision systems by leveraging scaling and dipolar flow estimators, thereby enabling the systematic quantification of collective flow at particle multiplicities previously inaccessible due to uncontrolled nonflow residuals.
This study employs the Faddeev approach within the Goldstone-boson-exchange relativistic constituent quark model to investigate how medium-induced parameter variations affect the mass spectrum of light and strange baryons, revealing that baryon masses are most sensitive to the quark-meson coupling constant and that even small mass shifts can significantly alter ideal-gas baryon yields.
This paper investigates the formation of light nuclei and hypernuclei in Au+Au collisions at using a parameter-free coalescence framework based on realistic -body wave functions, revealing species-dependent formation times and improving the description of yields through additional cluster-nucleon channels while providing predictions for heavier hypernuclei.
This paper proposes using the reconstructed invariant mass of kaons and half the deuteron four-momentum () as a direct experimental observable to distinguish between nucleon coalescence and statistical thermal models in deuteron production at the LHC, demonstrating that a resonance peak emerges only in the coalescence scenario.
This paper employs holographic duality to derive all-order constitutive relations for chiral plasma under strong magnetic fields, thereby analyzing transport phenomena such as negative magnetoresistance and chiral magnetic waves beyond the naive hydrodynamic limit.
This paper demonstrates that realistic microscopic wave functions for nuclear clusters and hypernuclei exhibit broader, non-Gaussian spatial distributions compared to Gaussian approximations, and proposes a mechanism using phenomenological two-body interactions to explain the underestimation of cluster yields in theoretical models.
Using the - fast-timing technique with the VENTURE array at VECC, Kolkata, researchers measured the lifetimes of low-lying negative-parity states in Gd to determine that their transition strengths are strongly hindered, providing evidence for weak dipole strength in octupole bands.
This paper investigates the role of the QCD scale anomaly in the nucleon's gravitational form factors using a scale-invariant Skyrme model, demonstrating that the inclusion of a scalar meson to represent gluonic contributions is crucial for satisfying nucleon stability conditions and accurately reproducing lattice QCD results for the form factor.
This paper proposes that rotating synchrotron radiation (RoSyRa) from a magnetized, rotating quark-gluon plasma generates a low-transverse-momentum photon spectrum with significant elliptic flow, offering a viable solution to the "direct photon puzzle."
This paper utilizes a Regge framework applied to high-energy polarized photoproduction data from GlueX to achieve the first complete determination of the vector and tensor couplings between the system and the , , and mesons.
