Heavy Hybrid Meson Masses derived from QCD sum rules in Heavy Quark Effective Theory
QCD sum rules are derived for the heavy hybrid mesons with one heavy quark and JPC = 1−+, 0++, 1+−, 0−− in the leading order of heavy quark effective theory. We obatin the binding energy ΛH = (1.1±0.1), (1.51±0.10), (1.28±0.10), (1.5±0.1) GeV and decay constant fH = (0.205± 0.02), (0.415 ± 0.04), (0.217 ± 0.02), (0.317 ± 0.03)GeV 7 2 for 1−+, 0++, 1+−, 0−− respectively when the light quark is u...
متن کاملHeavy-meson form factors from QCD sum rules.
A consistent framework is developed for studying hadronic form factors of heavy mesons using QCD sum rules in the heavy quark effective theory, including the-next-to-leading order renormalization group improvement. Sum rules are derived for the asymptotic value of the meson decay constant jp and for the universal Isgur-Wise form factor. It is shown that renormalization group effects considerabl...
متن کاملΠ-η Mixing from Qcd Sum Rules
The q2 dependence of the π-η mixing amplitude is examined with the use of QCD sum rules. The linear slope of the mixing function θ(q2) is found to be much smaller than that for ρ-ω mixing. Thus the mixing amplitude is approximately the same in the space-like region as in the time-like one, and one may neglect the q2 dependence of the mixing. A comparison between a hadron-meson, an effective chi...
متن کاملHeavy quark masses from QCD sum rules
I review recent determinations of the (on-shell) charmand beauty-quark masses in the framework of relativistic and non-relativistic ratios of Laplace transform QCD moment sum rules. The validity of the non-relativistic version of QCD sum rules in this particular application is discussed. Invited talk at the Mexican School of Particles and Fields, Villahermosa, Mexico, October 1994. John Simon G...
متن کاملExcited Heavy Mesons from Qcd Sum Rules
In this talk, we focus on the L = 1 excited charm mesons. It is heuristic to illustrate them in the following way, although it is not accurate (L is not a conserved quantity). For the ground state (L = 0) mesons which we are familiar with, there are two states with the J quantum numbers: D(0) and D(1). Their difference only lies in the heavy quark spin direction. For the L = 1 case, there are f...
