摘要: The mass spectra of the L = 1 orbitally excited heavy baryons with light quarks inboth the spin-flavor symmetric and the mixed representations are studied by the1/Nc expansion method in the framework of the heavy quark effective theory. The mixing effect between the baryons in the two representations is also considered.The general pattern of the spectrum is predicted which will be verified by theexperiments in the near future.
