英文摘要: The mass parameter of orbitally excited Lambda(c) baryons is calculated by using QCD sum rule in the framework of heavy quark effective theory. Two kinds of interpolating current for the excited heavy baryons are introduced. It is obtained that <(Lambda)over bar> = 1.08(-0.1040)(+.0945) GeV for the non-derivative current and <(Lambda)over bar> = 1.06(-0.107)(+0.090) GeV for the current with derivative. These results are consistent with experimental data. (C) 2000 Published by Elsevier Science B.V. All rights reserved.
