B -> Dlnu: ai_n (i = p —vector, 0 —scalar; n = 0,1,2,3) are free coefficients of z expansion in dispersion relation parametrization from C.G.Boyd, B.Grinstein, R.F.Lebed, Phys.

Rev. Lett. 74,4603(1995)

Chosen the order of series N=3, i.e. m_a_0 + m_a_1 * z + m_a_2 * z^2 + m_a_3 * z^3

Fitted values cited from R.Glattauer, etc. (Belle) Phys. Rev. D 93,032006 (2016).

B -> D*lnu: m_a_n, m_b_n (n = 0,1) and m_c_n (n = 0,1,2) are free coefficients of z expansion parametrization from C.G.Boyd, B.Grinstein and R.F.Lebed, Phys. Rev. D 56,6895(1997) & B.Grinstein, A.Kobach, Phys. Lett. B 771(2017)359-364

For the expansion of form factors g and f, the order of series N=1, i.e. m_a_0 + m_a_1*z For the expansion of form factors F1, the order of series N=2, i.e. m_c_0 + m_c_1 * z + m_c_2 * z**2 (g, f and F1 are the sub-terms of helicity amplitude)

Fitted values are taken from a private discussion of Florian Bernlochner based on B.Grinstein and A.Kobach, Phys. Lett. B 771(2017)359-364 0th-order z expansion coeffieient for vector form factor: f_+
