Lattice QCD yields continuum-limit HQET LCDA parameters λ_B = 0.340(20) GeV and σ_B^(1) = 1.685(63) at 1 GeV, reducing total uncertainty by a factor of three.
Continuum-extrapolated lattice QCD yields heavy-meson LCDAs with D-meson peak at y≈0.2-0.3 and HQET inverse moment λ_B=0.340(20) GeV at 1 GeV, consistent with other determinations.
Final-state rescattering predicts branching fractions for B0 and Bs0 to Lambda_c+ anti-Lambda_c- that match LHCb data, with near-zero CP asymmetries and sizable longitudinal polarization in the B0 channel.
