Conservation laws and sum rules in the heavy quark limit.
In the heavy quark limit, hadrons appear as eigenstates of the light degrees of freedom under the static color field of the heavy quark. In this formalism, the weak form factors appear naturally as the overlaps of the initial and final wavefunctions of the light degrees of freedom, and the Bjorken and Voloshin sum rules are statements of conservation of probability and energy. Moreover, parity ...
متن کاملMore conservation laws and sum rules in the heavy quark limit.
This is the continuation of a previous article in which the Bjorken and Voloshin sum rules were interpreted as statements of conservation of probability and energy. Here the formalism is extended to higher moments of the Hamiltonian operator. From the conservation of the second moment of the Hamiltonian operator one can derive a sum rule which, in the small velocity limit, reduces to the Bigi-G...
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 کاملRemarks on sum rules in the heavy quark limit of QCD
We underline a problem existing in the heavy quark limit of QCD concerning the rates of semileptonic B decays into P-wave D J (j) mesons, where j = 1 2 (wide states) or j = 3 2 (narrow states). The leading order sum rules of Bjorken and Uraltsev suggest Γ ¯ B → D 0,1 1 2 ℓν ≪ Γ ¯ B → D 1,2 3 2 ℓν , in contradiction with experiment. The same trend follows also from a sum rule for the subleading ...
متن کامل0 ( 2317 ) as a tetraquark state with QCD sum rules in heavy quark limit
In this article, we take the point of view that the charmed scalar meson Ds0(2317) be a tetraquark state and devote to calculate its mass within the framework of the QCD sum rules approach in the heavy quark limit. The numerical values for the mass of the Ds0(2317) are consistent with the experimental data, there must be some tetraquark component in the scalar meson Ds0(2317). Detailed discussi...
