AI 中文摘要
我们讨论了Born-Oppenheimer有效场论（BOEFT）形式体系的一些近期应用，该形式体系直接源自QCD，基于尺度分离和对称性，适用于包含两个重夸克的强子系统。这一形式体系通过耦合的薛定谔方程，对普通和奇异的夸克偶素态（即混合态、四夸克态、五夸克态等）的动力学提供了统一描述，其势能在格点上可计算。目的是揭示XYZ奇特强子的难以捉摸的规律。在此，我们将BOEFT形式体系应用于χc1(3872)、Tcc(3875)+及其底夸克对应态。此外，我们评估了阈值效应对夸克偶素谱的影响，并讨论了χc1(3872)的包含性产生截面。
英文摘要
We discuss some recent applications of the Born-Oppenheimer effective field theory (BOEFT) formalism, directly derived from QCD and grounded in scale separation and symmetries, to hadronic systems containing two heavy quarks. This formalism provides a unified description of both ordinary and exotic quarkonium states (i.e., hybrids, tetraquarks, pentaquarks, ...) dynamics via coupled Schrödinger equations, whose potentials are computable on the lattice. The aim is to unveil the elusive pattern of the XYZ exotic hadrons. Here, we apply the BOEFT formalism to the $χ_{c1}(3872)$, $T_{cc}(3875)^+$, and their bottom counterparts. Moreover, we assess the threshold effects on the quarkonium spectrum and discuss the inclusive production cross section for $χ_{c1}(3872)$.
