fBs from QCD sum rules
The decay constants of the pseudoscalar mesons B and Bs are evaluated from QCD sum rules for the pseudoscalar two-point function. Recently calculated perturbative three-loop QCD corrections are incorporated into the sum rule. An analysis in terms of the bottom quark pole mass turns out to be unreliable due to large higher order radiative corrections. On the contrary, in the MS scheme the higher...
متن کاملfB and fBs using NRQCD
This talk summarizes the quenched calculation of fB and fBs presented in [1]. The heavy quark is simulated using an O(1/M) improved NRQCD action, and the tadpole improved clover action is used for the light quarks. The axial current includes the O(1/M) corrections in one-loop perturbation theory and the O(1/M) ones at tree-level. We discuss the various systematic effects and consistency checks ...
متن کاملWhat predicts continued substance use among probationers?
Methods Substance-using probationers (N =194) completed baseline and 2-month follow-up interviews. Probationers averaged 35 years-old and were predominately male (69%) and nonwhite (79%). Measures included demographics (e.g., age), treatment/use experience (e.g., ASI drug score), psychosocial functioning (e.g., self-esteem), and criminal justice experience (e.g., lifetime arrests). Hard drug us...

The complete model included Innovativeness as the strategic orientation of the firm, firm size, industry, and business strategy (See Figure 2). For a complete description of all the variables measured in this study the reader is referred to an earlier research brief. Results The anticipated relationships were supported by our analyses. Business strategy was not found to impact the relationship ...
