论文摘要
我们应用了新开发的NRQCD分解公式来分析完全融合的Tetraquark $ t_ {4c} $的独家生产以及$ b $工厂的硬光子。为简单起见，在这项工作中，我们集中于$ 0^{++} $的相关生产，$ 2^{++} $ tetraquarks带有光子。有了一些关于未知非扰动NRQCD矩阵元素大小的粗略估计，我们预测这些类型的独家通道的生产速率在$ \ sqrt {s} = 10.6 $ GEV上，还评估了他们在{\ tt belle 2}实验时的观察前景。
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.
