Abstract
The mass parameter of orbitally excited Λc 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 Λ̄=1.08+0.095−0.104 GeV for the non-derivative current and Λ̄=1.06+0.090−0.107 GeV for the current with derivative. These results are consistent with experimental data.
