نویسنده
چکیده
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. PACS number: 12.39.Hg, 14.20.Lq, 13.75.Gx, 12.38.Lg

Couplings of Pions with Excited Heavy Mesons From Light-Cone QCD Sum Rules in the Leading Order of HQET
The couplings of pions with lowest three doublets (0−, 1−), (0+, 1+) and (1+, 2+) of heavy mesons are studied with light-cone QCD sum rules in the leading order of heavy quark effective theory. The ambiguity due to presence of two distinct 1+ states are solved. PACS number: 12.39.Hg, 14.40.Nd, 12.38.Lg

متن کاملIntroduction to the Heavy Quark Effective Theory
Heavy Quark Effective Theory (HQET) is a new approach to QCD problems involving a heavy quark. In the leading approximation, the heavy quark is considered as a static source of the gluon field; 1/m corrections can be systematically included in the perturbation theory. New symmetry properties not apparent in QCD appear in HQET. They are used, in particular, to obtain relations among heavy hadron...
متن کاملQCD Interactions of Heavy Mesons with Pions by Light-Cone Sum Rules
Light-cone QCD sum rules are employed to compute the strong coupling constants: gB∗B∗π, gB1B0π and gB1B∗π, where (B,B ∗) and (B0, B1) are negative and positive parity (0−, 1−) and (0+, 1+) q̄Q doublets. The couplings are calculated both for finite values of the heavy quark mass and in the infinite heavy quark mass limit, deriving sum rules for mQ → ∞. PACS:11.55.Hx,13.20.He
متن کاملρ-Decay Widths of Excited Heavy Mesons From Light-Cone QCD Sum Rules in the Leading Order of HQET
The couplings and decay widths of the processes (1+, 2+) → (0−, 1−) + ρ are studied with the light-cone QCD sum rules in the leading order of heavy quark effective theory. These processes are employed to estimate the two pion transition widths of the (1+, 2+) doublet through the low mass tail of the ρ resonance. The ambiguity due to the presence of two distinct 1+ states is solved. Our calculat...
