|Vcb| from OPE Sum Rules for Heavy Flavor Transitions
We derive a model-independent upper bound for the axial-vector form factor of the B → D transition at zero recoil, FB→D∗ . The form factor turns out to be noticeably less than unity. The deviation of FB→D∗ from unity is larger than previously anticipated. Using our estimate we extract |Vcb| from the measured exclusive rate of B → Dlν extrapolated to the point of zero recoil. The central “ exclu...
متن کاملHeavy flavor decays, OPE and duality in two-dimensional ’t Hooft model
The ’t Hooft model (two-dimensional QCD in the limit of large number of colors) is used as a laboratory for exploring various aspects of the heavy quark expansions in the nonleptonic and semileptonic decays of heavy flavors. We perform a complete operator analysis and construct the operator product expansion (OPE) up to termsO(1/mQ), inclusively. The OPE-based predictions for the inclusive widt...
متن کاملSum Rules for Heavy Flavor Transitions in the SV Limit
We show how sum rules for the weak decays of heavy flavor hadrons can be derived as the moments of spectral distributions in the small velocity (SV) limit. This systematic approach allows us to determine corrections to these sum rules, to obtain new sum rules and it provides us with a transparent physical interpretation; it also opens a new perspective on the notion of the heavy quark mass. App...
متن کاملDoubly Heavy Systems: Decays and Ope
We discuss questions related to the application of OPE for the long-lived systems with two heavy flavors. The values of quark masses entering such calulations are constrained by use of currently available data on the lifetimes of B d and B c-mesons. The lifetimes of doubly charmed baryons at these values of parameters are evaluated. The necessary comments on the difference in the results obtain...
متن کاملQCD resummation and heavy quark cross sections
of the Dissertation QCD resummation and heavy quark cross sections by Nikolaos Kidonakis Doctor of Philosophy in Physics State University of New York at Stony Brook 1996 In this dissertation a detailed analysis of heavy quark production is given with an emphasis on the resummation of soft gluon corrections. First we calculate the production cross sections for top quark production at the Fermila...
