Decay constants of P - wave heavy - light mesons from unquenched lattice QCD
نویسندگان
چکیده
We review some decays that require knowledge of the decay constants of 0 + heavy-light mesons. We compute the decay constants of P-wave heavy-light mesons from unquenched lattice QCD at a single lattice spacing. For the charm-strange meson we obtain the decay constant: fD s 0 + = 340(110) MeV using our normalisation conventions. We obtain the f static Ps (static-strange P-wave) decay constant as 302(39) MeV.

We test the one-loop chiral perturbation theory formula on unquenched lattice data of pseudoscalar meson decay constants. The chiral extrapolation including the effect of the chiral logarithm is attempted and its uncertainty is discussed.

We present results for the static-light meson from unquenched lattice QCD. The unquenched gauge configurations were generated using the non-perturbatively improved clover action. At the fixed lattice spacing of 0.1 fm the lightest sea quark mass used is a third of the strange quark mass. A comparison is made between heavy-light chiral perturbation theory and the f B decay constant. The mass of ...
متن کاملQuenched Chiral Corrections to Heavy-Light Decay Constants at Order 1/M
Quenched chiral perturbation is used to study the decay constants for heavy-light mesons beyond the leading order in 1/M . The results are used to estimate the error in quenched lattice calculations of the decay constants. For the double ratio R1 = (fDs/fD)/(fBs/fB) we find that the error is small — conservatively 5%, but likely smaller. We also find that quenching decreases the ratio fDs/fD re...

In quark modelsà la Bakamjian and Thomas, that yield covariance and Isgur-Wise scaling of form factors in the heavy quark limit, we compute the decay constants f (n) and f (n) 1/2 of S-wave and P-wave mesons composed of heavy and light quarks. Heavy quark limit scaling √ M f = Cst. is obtained, and it is shown that this class of models satisfies the sum rules involving decay constants and Isgur...

The form factors for the semileptonic decays of heavy-light pseudoscalar mesons of the type D ! Kee are studied in quenched lattice QCD at = 6:0 using Wilson fermions. We explore new numerical techniques for improving the signal and study O(a) corrections using three diierent lattice transcriptions of the vector current. We present a detailed discussion of the relation of these lattice currents...
