QCD Interactions of Heavy Mesons with Pions by Light-Cone Sum Rules
نویسنده
چکیده
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

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 کاملBπ form factors from QCD Sum Rules
The H * Hπ form factor for H = B and D mesons is evaluated in a QCD sum rule calculation. We study the Borel sum rule for the three point function of two pseudoscalar and one vector meson currents up to order four in the operator product expansion. The double Borel transform is performed with respect to the heavy meson momenta. We discuss the momentum dependence of the form factors and two diff...
متن کاملMagnetic and quadrupole moments of light spin–1 mesons in light cone QCD sum rules
The magnetic and quadrupole moments of the light–vector and axial–vector mesons are calculated in the light cone QCD sum rules. Our results for the static properties of these mesons are compared with the predictions of lattice QCD as well as other approaches existing in the literature.
