quarkonium 中文意思是什麼
quarkonium
解釋
夸克偶素-
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
采納庫侖勢源於單膠子直接交換，而線性禁閉源於標量和矢量的混合，同時考慮在短程區域與單膠子直接交換起同樣作用的同味正反夸克的湮滅，構造了靜態夸克-反夸克勢到v ~ 2 c ~ 2級次的完全相對論修正，並擬合計算了重介子偶素的能譜，討論了相對論修正對重介子偶素能級分裂的作用。 -
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
由規范場理論的超弦理論所激發的伸縮子一膠子有效藕合，給出了一個新的靜態夸克一反夸克勢，討論了此勢模型下重介子的自旋平均能譜、輕子衰變和輻射躍遷寬度，並與cdrn叭勢模型所得到的相應結果作了比較 -
Heavy quarkonium properties are studied in the relativistic quark model based on the quasipotential approach in the quantum field theory
本文在量子場論中基於準勢途徑的相對論夸克模型中研究了重夸克偶素的性質。 -
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
