标题： $B \to ρ\ell ν_\ell$ Form Factors

摘要： TO_BE_TRANSLATED: The bounds on the form factors for $B \to \rho \ell \nu_\ell$ decay are studied. Constrained by lattice data and a constrained conformal mapping, the more informations can be obtained for $A_1(q^2)$ form-factor which dominates the decay rate at large $q^2$. Specifically, we confirm a moderately increasing behavior of this form factor. 显示英文摘要
