论文摘要
随着第一个数据记录在Belle II，我们处于夸克风味物理学的新时代的边缘。 Belle〜II的许多令人兴奋的新机会包括对包容性$ {\ bar b \ to x_ {s} \，\ ell^+\ ell^ - } $的完整角度分析，该分析有可能揭示新物理学，特别是通过与S \ ell^ell^+ell^+ell^+\ ell^+\ ell^ - $ $ $ $ $ $ $ $ $ $ $ $ b \相互作用。在本文中，我们为所有努力所需的所有角度可观察物提供了完全更新的标准模型预测。这些预测是针对Belle II量身定制的，包括对共线光子治疗的精心研究，这些研究在瞄准最高精度时变得至关重要。此外，我们还提供了一项现象学研究，以独立的方式和与独家模式结合使用Belle II在包容性衰减通道中可能新物理学的潜力。
With the first data being recorded at Belle II, we are at the brink of a new era in quark flavour physics. The many exciting new opportunities for Belle~II include a full angular analysis of inclusive ${\bar B \to X_{s} \, \ell^+\ell^-}$ which has the potential to reveal new physics, in particular by its interplay with the exclusive $b \to s \ell^+\ell^-$ counterparts studied extensively at LHCb. In this paper, we present fully updated Standard Model predictions for all angular observables necessary for this endeavour. These predictions are tailored to Belle II and include an elaborate study of the treatment of collinear photons which become crucial when aiming for the highest precision. In addition, we present a phenomenological study of the potential for Belle II to reveal possible new physics in the inclusive decay channel, both in an independent manner and in combination with exclusive modes.
