QCD sum-rule computation of vector/axial-vector and tensor/axial-tensor decay constants for B_c, B_c*, B_c0*, B_c1 mesons, with refined power corrections and first tensor results.
Reviews unitarity bounds for B-meson form factors, shows standard methods apply rigorously only to B→π, develops GG parametrization for general cases, and delivers combined-analysis predictions with public supplementary material.
LCSR calculations give M1 radiative widths for K*, D*, B*, D_s*, B_s*, and ψ(2S), matching K* data and yielding a fitted universal log-log scaling with A(2.1).
