42. Nucleon structure from holographic QCD

We employ the Veneziano quantum chromodynamics (VQCD) model, a holographic approach that dynamically simulates essential QCD characteristics, including linear mass spectra, confinement, asymptotic freedom, and magnetic charge screening, while incorporating quark flavor effects. Using this model, we first calculate the proton mass spectrum and the wave function, incorporating anomalous...

67. A deep learning approach for predicting multiple observables in Au+Au collisions at RHIC

We develop a neural network model, based on the processes of high-energy heavy-ion collisions, to study and predict several experimental observables in Au+Au collisions. We present a data-driven deep learning framework for predicting multiple bulk observables in Au+Au collisions at RHIC energies. A single neural network is trained exclusively on experimental measurements of charged-particle...

We develop a theoretical framework for the production of K+K- pairs through the decay of ϕ mesons produced from a thermal background, based on the Nambu-Jona-Lasinio (NJL) model. The differential production rate of K+K- is related to the self-energy of the ϕ meson, incorporating the contributions of the quark loop at...

40. 一类分段光滑不连续映象中的边界碰撞分岔和余维分岔

本文研究了一类分段光滑不连续一维映象的动力学。当周期轨道失稳时，系统会进入混沌状态。而不连续性的出现导致了边界碰撞分岔的发生，可以使稳定的周期轨道转变为混沌状态或者另外一个稳定的周期状态。在这类转变点的附近，常常伴随着吸引子共存现象。 此外，随控制参数减小出现周期递增现象。得到了求解这类不连续映象在任意参数下边界碰撞分岔临界控制参数的一般方法。基于稳定性和边界碰撞分岔的解析分析, 获得了双参数平面中系统动力学的相平面, 讨论了系统的动力学行为，发现了三类余维-2分岔点， 并给出了其坐标通式。同时，在相平面中还发现了余维分岔点的融合，构成一类特殊的三相点，并解析得到其存在的条件。

41. CGC-induced longitudinal ridge in p-Pb collisions

路华 邱 (华中师范大学博士研究生)

27/11/2025, 15:00

Within the Color Glass Condensate (CGC) effective field theory, we investigate the long-range rapidity correlations in proton-lead (p-Pb) collisions at √ s NN = 5.02 TeV. As expected, the long-range rapidity correlations rebound after bottoming, which is successfully reproduced by the CGC. It is also found that the correlation rebound appears around the sum of the saturation momenta of the...
