In phenomenological side, all possible couplings of interpolating current to hadronic states are considered. In QCD side, the perturbative part and the contributions of vacuum condensates up to dimension 8 are also included. With the estimated form factors, we study the decay widths and branching ratios of semileptonic decays $\\Lambda_b\\to\\Lambda_cl\\bar{\\nu}_l$ and $\\Xi_b\\to\\Xi_cl\\bar{\\nu}_l$ ($l=e,\\mu$ and $\\tau$).
