标题： Exclusive radiative production of fully-charmed tetraquarks at $B$ Factory

摘要： 我们将新发展的NRQCD因子化公式应用于分析在$B$工厂中完全含重夸克的四夸克态$T_{4c}$与硬光子的独占产生。 为了简化，在这项工作中我们集中研究了$0^{++}$和$2^{++}$四夸克态与光子的关联产生。 通过对未知非微扰NRQCD矩阵元大小的一些粗略估计，我们预测了这些类型独占通道在$\sqrt{s}=10.6$GeV处的产生率，并评估了它们在{\tt Belle 2}实验中被观测的可能性。 显示英文摘要

摘要： We apply the newly developed NRQCD factorization formula to analyze the exclusive production of the fully-charmed tetraquark $T_{4c}$ plus a hard photon at $B$ factory. For simplicity, in this work we have concentrated on the associated production of the $0^{++}$ and $2^{++}$ tetraquarks with a photon. With some rough estimates about the size of the unknown nonperturbative NRQCD matrix elements, we predict the production rates of these types of exclusive channels at $\sqrt{s}=10.6$ GeV and also assess their observation prospect at {\tt Belle 2} experiment.
