摘要:
强子共振态在我们理解标准模型中的重要性日益增加,这一点得到了格点量子色动力学(QCD)计算近期进展的强调。我们回顾了近期的发展,特别着重于导致双强子末态的电弱跃迁。此外,我们结合 $B\to ππ\ell\barν$ 的初步结果,介绍了在此类研究中至关重要的有限体积格点 QCD 方法。
英文摘要:
The increasing importance of hadronic resonances in our understanding of the Standard Model is underscored by recent advancements in lattice Quantum Chromodynamics (QCD) calculations. We review recent developments, with a particular emphasis on electroweak transitions that result in two-hadron final states. Additionally, we present the finite-volume lattice QCD methodologies that are pivotal in such studies in the context of preliminary results from the $B\to ππ\ell\barν$.
