quarkonium meaning in Chinese
夸克偶素
Examples
- Heavy quarkonium properties are studied in the relativistic quark model based on the quasipotential approach in the quantum field theory
本文在量子场论中基于准势途径的相对论夸克模型中研究了重夸克偶素的性质。 - First , the cornell potential is used widely as phenomenological potentail and takes rather success in explaining the heavy quarkonium properties . the problem is how to consider the relativistic corrections to this potential
如何考虑这个静态势的相对论修正，核心的问题是如何处理夸克-反夸克相互作用的洛仑兹结构。 - Adopting the assummation that the quark interaction is the sum of the usual one - gluon direct exchange and the mixture of linear scalar and vector potentials , we structure the relativistic corrections of order v2 / c2to the cornell potential , including the annihilation potential for the quark and antiquark of the same favors which plays the same role with the one - gluon direct exchange at short distances . the effects of the relativistic corrections on the hyperfine splittings of quarkonium states are discussed , and a good fit to the available experimental data is obtained on heavy quarkonium mass spectra
采纳库仑势源于单胶子直接交换，而线性禁闭源于标量和矢量的混合，同时考虑在短程区域与单胶子直接交换起同样作用的同味正反夸克的湮灭，构造了静态夸克-反夸克势到v ~ 2 c ~ 2级次的完全相对论修正，并拟合计算了重介子偶素的能谱，讨论了相对论修正对重介子偶素能级分裂的作用。 - We obtain a new quark potential from the effective dilaton - gluon - coupling inspired by superstring theory , and by using this static potential , we explore the mechanism of quark confinement through calculations of the spin - average energy levels , the widths of the leptonic decays and radiative transitions for heavy quarkonium . the obtained results are compared with that of the cornell potenial
由规范场理论的超弦理论所激发的伸缩子一胶子有效藕合，给出了一个新的静态夸克一反夸克势，讨论了此势模型下重介子的自旋平均能谱、轻子衰变和辐射跃迁宽度，并与cdrn叭势模型所得到的相应结果作了比较
