Abstract
We calculate B(s), and D(s) to K*0(1430) transition form factors, and study semileptonic decays of B(s) and D(s) → K0*(1430)ℓ̄ν based on QCD sum rule. Measuring these semileptonic decays with high statistics will give valuable information on the nature of light scalar mesons.

Then, we can calculate the differential decay widths of the semileptonic decays $B_s,D_s→K_0^∗(1430) ℓν_ℓ$ with the following formula [ref] [equation] In calculation, we take the fermi coupling constant $G_F = 1.166 ×10^-5 GeV^-2$, CKM Matrix elements $|V_ub| = (3.82 ±0.20) ×10^-3$, $|V_cd| = 0.221 ±0.004$, $m_ℓ$ denotes the lepton mass and $m_e = 0.511 ×10^-3 MeV$, $m_μ= 105.658 ×10^-3 MeV$ and $m_τ= 1776.86×10^-3 MeV$ [ref] .
