Two-Loop Relations for Heavy-Quark Parameters in the Shape-Function Scheme
Moments of the renormalized B-meson shape function provide a natural way to define short-distance, running heavy-quark parameters such as the b-quark mass and kinetic energy. These parameters are particularly well suited for studies of inclusive decay distributions. The definitions of mb and μ 2 π in this “shape-function scheme” are derived to two-loop order. Using previous determinations of he...
متن کاملTwo-Loop Matching Coefficients for Heavy Quark Currents
In this paper we consider the matching coefficients up to two loops between Quantum Chromodynamics (QCD) and Non-Relativistic QCD (NRQCD) for the vector, axial-vector, scalar and pseudo-scalar currents. The structure of the effective theory is discussed and analytical results are presented. Particular emphasis is put on the singlet diagrams. PACS numbers: In the recent years quite a lot of acti...
متن کاملTHE ROLE OF QUARK POLARIZATION IN HEAVY QUARK FRAGMENTATION
We calculate the exact fragmentation functions for c and b quark fragmentation taking into account the spin orientation of the initial heavy quark in the form of analytical and rather simple expressions. Our calculations show that spin orientation may have an important effect on the fragmentation spectrum. This effect is more striking in the cases of c ?D, D*; c? ? , ? , and ?B , B *.
متن کاملExact Relations for Heavy-Light Quark Systems
We derive general relations among hadronic form factors involving one heavy meson bq and another, not necessarily heavy, meson Qq. The relations are valid to all orders of mass corrections of mQ .
متن کاملA quark loop model for heavy mesons
I consider a model based on a quark–meson interaction Lagrangian. The transition amplitudes are evaluated by computing diagrams in which heavy and light mesons are attached to quark loops. The light chiral symmetry relations and the heavy quark spin-flavour symmetry dictated by the heavy quark effective theory are implemented. The model allows to compute the decay form factors and therefore can...
