Precision calculations of $B_{d,s}\to \pi ,K$ decay form factors in soft-collinear effective theory

Bo-Yan Cui, Yong-Kang Huang, Yue-Long Shen +2

We improve QCD calculations of the $B_{d,s}\to \pi ,K$ form factors at large hadronic recoil by implementing the next-to-leading-logarithmic resummation for the obtained leading-po…
