AbstractThe more precise extraction for the CKM matrix element \V-cb\ in the heavy quark effective field theory (HQEFT) of QCD is studied from both exclusive and inclusive semileptonic B decays. The values of relevant nonperturbative parameters up to order 1/m(Q)(2) are estimated consistently in HQEFT of QCD. Using the most recent experimental data for B decay rates, \V-cb\ is updated to be \V-cb\ = 0.0395 +/- 0.0011(expt +/-) 0.0019(theor) from B --> D*lv decay and \V-cb\ = 0.0434 +/- 0.0041(expt) +/- 0.0020(theor) from B --> Dlv decay as well as \V-cb\ = 0.0394 +/- 0.0010(expt) +/- 0.0014(theor) from inclusive B --> X(c)lv decay.
