| 英文摘要 | The leading Isgur-Wise form factor xi (y) parametrizing the semileptonic transitions Lambda (b) --> Lambda (1/2)(cl)l<()over bar> and Lambdab --> Lambda (3/2)(cl)l<()over bar> is calculated by using the QCD sum rules in the framework of heavy quark effective theory, where Lambda (1/2)(cl) and Lambda (3/2)(cl) is the orbitaIly excited charmed baryon doublet with J(P) = (1(-)/2, 3(-)/2). The interpolating currents with transverse covariant derivative are adopted for Lambda (1/2)(cl) and Lambda (3/2)(cl) in the analysis. The slope parameter rho (2) in linear approximation of the Isgur-Wise function is obtained to be rho (2) = 2.01, and the interception to be xi (1) = 0.29. The decay branching ratios are estimated.
