B→πℓ+ℓ− form factors reexamined in the whole kinematically accessible region

We reexamine the B→πℓ+ℓ−(ℓ=e,μ,τ) form factors, f+B→π(q2), f0B→π(q2) and fTB→π(q2), in the entire region of the momentum transfer squared q2, by taking advantage of the complementarity between lattice QCD (LQCD) simulation and light cone sum rule approach (LCSR), and analyticity of the form factors....
