论文摘要
Quarkonium Wave功能中的$ d $ - 波混合物是从$ v \到q \ bar q $ transition在文献中广泛使用的光框中获得的。这种$ d $ - 波镇的镇流器没有任何非依赖主义模型的合理性，$ q- \ bar q $相互作用潜力，并导致对超夸克产物中超质量Quarkonium生产的跨部门的伪造预测。我们通过基于简单的非Photon样本“ $ s $ - wave-folly” $ v \ to q \ bar q $ truntition在$ q \ bar q $ rether框架中的q \ bar q $转换，分析了$ d $ - 波的贡献的负面作用。
The $D$-wave admixture in quarkonium wave functions is acquired from the photonlike structure of $V\to Q\bar Q$ transition in the light-front frame widely used in the literature. Such a $D$-wave ballast is not justified by any nonrelativistic model for $Q-\bar Q$ interaction potential and leads to falsified predictions for the cross sections in heavy quarkonium production in ultra-peripheral nuclear collisions. We analyze this negative role of $D$-wave contribution by comparing with our previous studies based on a simple non-photon-like "$S$-wave-only" $V\to Q\bar Q$ transition in the $Q\bar Q$ rest frame.
