We give a comprehensive account of the flavour physics of Beyond-Standard-Model (BSM) effects in $b \to c \bar{c} s$ transitions, considering the full set of 20 four-quark operators. We discuss the leading-order structure of their RG mixing with each other as well as the QCD-penguin, dipole, and FCNC semileptonic operators they necessarily mix with, providing compact expressions. We also provide the first complete results for BSM effects in the lifetime observables $\Delta \Gamma_s$ and $\tau(B_s)/\tau(B_d)$, as well as for the semileptonic CP-asymmetry $a_{sl}^s$. From a global analysis, we obtain stringent constraints on 16 of the 20 BSM operators, including the 10 operators $Q^{c\prime }_{1 \dots 10}$ involving a right-handed strange quark. Focussing on CP-conserving new physics, the constraints correspond to NP scales of order 10 TeV in most cases, always dominated by exclusive and/or radiative $B$-decays via RGE mixing. For the remaining four operators, including the two Standard-Model (SM) ones, larger effects are experimentally allowed, as previously noted in arXiv:1701.09183. We extend that paper's scope to the CP-violating case, paying attention to the impact on the decay rate and time-dependent CP-violation in $B_d \to J/\psi K_S$. We show that quantifiable constraints arise for new physics in either of the two SM operators, with the uncertain non-perturbative matrix element of the colour-suppressed operator determined from the data. For new physics in the SM suppressed coefficient $C^c_1$ we find two perfectly viable, narrow bands of complex Wilson coefficients. Somewhat curiously, one of them contains a region where the fitted matrix element for the colour-suppressed operator is in agreement with naive factorization, contrarily to a widely held belief that large non-factorizable contributions to $B_d \to J/\psi K_S$ are implied by experimental data.

迷人的新 B-physics

考虑到 20 个四夸克算子的完整集合，我们全面介绍了 $b \to c \bar{c} s$ 转换中的超标准模型 (BSM) 效应的风味物理。我们讨论了它们相互混合的 RG 的前导结构，以及它们必须混合的 QCD-企鹅、偶极子和 FCNC 半轻算子，提供了紧凑的表达式。我们还提供了生命周期观测值 $\Delta \Gamma_s$ 和 $\tau(B_s)/\tau(B_d)$ 中 BSM 效应的第一个完整结果，以及半轻 CP 不对称 $a_{sl}^ s$。从全局分析中，我们获得了对 20 个 BSM 算子中的 16 个的严格约束，包括涉及右手奇异夸克的 10 个算子 $Q^{c\prime }_{1 \dots 10}$。专注于CP-conserving新物理，在大多数情况下，约束对应于 10 TeV 量级的 NP 尺度，总是由通过 RGE 混合的排他和/或辐射 $B$-衰变主导。对于其余四个算子，包括两个标准模型 (SM) 算子，实验允许更大的影响，如之前在 arXiv:1701.09183 中所述。我们将该论文的范围扩展到违反 CP 的情况，注意对 $B_d \to J/\psi K_S$ 中衰减率和时间相关的 CP 违反的影响。我们表明，在两个 SM 算子中的任何一个中，新物理学都会出现可量化的约束，颜色抑制算子的不确定非微扰矩阵元素由数据确定。对于 SM 抑制系数 $C^c_1$ 中的新物理学，我们发现两个完全可行的窄带复数威尔逊系数。有点好奇，
