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. Our team transforms dense academic manuscripts into clear, plain-language summaries alongside detailed technical overviews, ensuring that both experts and curious readers can grasp the latest breakthroughs without getting lost in the jargon. Below are the latest papers in nuclear theory, distilled and ready for you to explore.
Based on recent lattice evidence and 't Hooft anomaly constraints, this paper proposes that the chiral phase transition in hot QCD for massless flavors may be described by a conformal manifold of -dependent universality classes featuring an exactly marginal operator related to baryon density, rather than a standard Ginzburg-Landau critical point.
The JETSCAPE Collaboration employs Bayesian Inference with Active Learning to determine the jet transport parameter in the Quark-Gluon Plasma by simultaneously analyzing inclusive hadron and jet suppression data from RHIC and LHC, revealing systematic tensions that offer new insights into jet transport physics.
This paper investigates how rotation influences the anisotropic shear viscosity and electrical conductivity of strongly interacting matter by employing kinetic theory within Hadron Resonance Gas and Nambu-Jona-Lasinio models, revealing that rotation suppresses chiral condensates, generates a sizable Hall-like conductivity, and reduces transport coefficients relative to isotropic cases.
This paper investigates the relationship between the compositeness of shallow bound states and scattering observables using a coupled-channel potential model that incorporates both quark and hadron degrees of freedom, with a specific focus on applying this framework to analyze the internal structure of exotic hadrons such as the , , , and .
This study presents a precision measurement of bremsstrahlung gamma rays in Sn+Sn collisions at 25 MeV/u using the CSHINE spectrometer, establishing a robust experimental framework to extract a high momentum tail fraction of and demonstrating the feasibility of probing short-range correlations in low-energy heavy-ion reactions.
This study utilizes a hybrid hydrodynamic-transport model to simulate Pb+Pb collisions at 2.76 TeV, demonstrating that the coalescence mechanism for deuteron production provides a better description of experimental elliptic flow data than direct thermal production.
This paper demonstrates that the Richardson-Lucy algorithm effectively reconstructs three-dimensional pion emission sources from heavy-ion collision data, revealing their sensitivity to the initial neutron skin thickness and establishing the method as a viable tool for probing neutron density distributions in heavy nuclei.
This paper introduces a generalized Gross-Pitaevskii equation with logarithmic density-dependent coupling to model 2D attractive Bose systems, enabling the theoretical analysis of quantum droplets, breathing modes, quench dynamics, and universal excited states while providing a robust framework for future experimental investigations.
This paper demonstrates that neglecting heat flux in relativistic Couette-type flows leads to qualitatively incorrect profiles due to the "inertia of heat," a phenomenon where heat flux contributes to momentum density and necessitates energy transport across boundaries to balance viscous heating.
This paper proposes a novel solution to the hyperon puzzle by using the Dyson-Schwinger equation approach to incorporate quantum many-body effects, resulting in a stiff equation of state that supports neutron stars up to 2.59 solar masses while suppressing rapid cooling mechanisms.
