We revisit electroweak radiative corrections to Standard Model Effective Field Theory (SMEFT) operators which are relevant for the B-meson semileptonic decays. The one-loop matching formulae onto the low-energy effective field theory are provided without imposing any flavor symmetry. The on-shell conditions are applied especially in dealing with quark-flavor mixings. Also, the gauge independence is shown explicitly in the R_ξ gauge.

再次探讨SMEFT中对b→sℓℓ的电弱辐射校正

我们重新研究对B型介子半轻子衰变相关的标准模型有效场论（SMEFT）算子的电弱辐射校正。在不施加任何风味对称性的情况下，提供了低能有效场理论上的单环匹配公式。带壳条件特别适用于处理夸克-香精混合。此外，计独立性在明确示出ř _ξ计。
