Couplings of pions with heavy baryons from light-cone QCD sum rules in the leading order of HQET

The couplings of pions with heavy baryons g2(Σ∗,Σ) and g3(Σ∗,Λ) are studied with light-cone QCD sum rules in the leading order of heavy quark effective theory. Both sum rules are stable. Our results are g2=1.56±0.3±0.3, g3=0.94±0.06±0.2.
