粲偶素的辐射跃迁
Towards Radiative Transitions in Charmonium
摘要：
我们提出了初步的计算对粲偶素辐射跃迁使用各向异性$N_f = 2 + 1$动力学合奏产生的强子谱合作。随着新技术的使用，我们的目标是调查国家之间的过渡，包括潜在的异国情调的charmonium状态，躺在光谱比以前的研究。在这项工作中的一个重要组成部分是使用变分优化的插值算子，允许一个可靠的确定三点关联函数需要。使用这些运营商，我们执行的第一个计算相关的三点关联函数，然后再讨论未来的方向。
英文摘要：
We present preliminary calculations towards radiative transitions in charmonium using anisotropic $N_f = 2 + 1$ dynamical ensembles generated by the Hadron Spectrum Collaboration. With the use of newer technologies we aim to investigate transitions between states, including potential exotic charmonium states, lying higher in the spectrum than in previous studies. A crucial ingredient in this work is the use of variationally optimised interpolating operators which allow for a reliable determination of the three-point correlation functions needed. Using these operators, we perform first calculations of relevant three-point correlation functions before discussing future directions.
