晶格QCD可以通过提供b -> K（*）形式因子的第一性原理计算，为寻找b ->衰变的新物理做出贡献。这里提出了初步结果，通过在大q^2下完成来补充和规则确定，并通过直接在物理b扇区对未淬火规范场配置进行工作来改进先前的晶格计算。
Lattice QCD can contribute to the search for new physics in b -> s decays by providing first-principle calculations of B -> K(*) form factors. Preliminary results are presented here which complement sum rule determinations by being done at large q^2 and which improve upon previous lattice calculations by working directly in the physical b sector on unquenched gauge field configurations.
