论文摘要
最近观察到Tetraquark $ t_ {cc}^+ $状态的动机，在这项工作中，我重新访问了重型理论的有效理论，以对可能的deuteron类似deuteron的$ d^{（\ ast）} d^{（\ ast）} {（\ ast）}，\ bar \ bar {b} = \ bar {b}^{（\ ast）} $和$ d^{（\ ast）} \ bar {b}^{（\ ast）} $分子。特别是，使用$ t_ {cc}^+ $的数据作为输入来固定与浅层结合的$ d d^{*} $ System与$ i（j^p）= 1（1^+）$相关的潜在，分析了在双重魅力范围内形成其他松散结合状态的条件。还讨论了其他部门。
Motivated by the recently observation of the tetraquark $T_{cc}^+ $ state, in this work I revisit the Heavy-Meson Effective Theory to perform a simplified field-theoretical study of possible deuteron-like $D^{(\ast)} D ^{(\ast)}, \bar{B}^{(\ast)} \bar{B}^{(\ast)} $ and $D^{(\ast)} \bar{B}^{(\ast)} $ molecules. In particular, using the data from $T_{cc}^+ $ as input to fix the potential associated to the shallow-bound $ D D^{*} $ system with $I(J^P) = 1(1^+)$, the conditions for the formation of other loosely-bound states in the doubly charmed sector are analyzed. The other sectors are also discussed.
