Using the heavy quark antiquark potential which emerges from an effective dilaton gluon coupling inspired by the superstring theory, we study the energy levels of heavy quark antiquark systems. 使用从超弦理论激发的伸缩子与胶子耦合的有效理论得出的重夸克反夸克势,研究了重夸克反夸克系统的自旋平均能级。
On the Dynamical Fluctuations Inside Quark and Antiquark Jets Produced in e~+ e~-Annihilation 正负电子湮灭中正反夸克喷注内部动力学起伏的研究
The structures of(Ω) LST systems are studied in the SU ( 3) quark model, in which the coupling between quark antiquark and the meson fields is included. 从夸克-反夸克通过介子场耦合的模型出发研究了(ΩN)LST是否存在束缚态的问题。
A pair of constituent quarks of colliding hadrons in such processes will be resolved into a bare quark ( or antiquark) and a lot of non-perturbative gluons ( and quark pairs). 对撞强子中的一对组分夸克被分解为裸夸克和一系列非微扰胶子(和夸克对)。
The spin distribution of nucleon has been investigated extensively since the fact that only a small fraction of spin is from quark and antiquark was observed in an experiment performed by European Muon Collaboration ( EMC). 自从欧洲μ子中心EuropeanMuonCollaboration(EMC)在实验上观察到核子的自旋仅有一小部分来自夸克和反夸克,核子自旋分布情况的研究便逐渐深入。
For the recombination model, we consider only quark and antiquark degrees of freedom, and gluons are assumed to have been converted into quark and antiquark pairs before hadronization. 在重组合模型中只考虑夸克和反夸克,胶子并不直接参与重组合,认为在强子化前胶子已经转化成夸克和反夸克对。
