Lattice 2008
Recent measurements of the branching fraction for D s → ν disagree with the Standard Model expectation, which relies on calculations of f D s from lattice QCD. This paper uses recent preliminary measurements from CLEO and a new preliminary lattice-QCD result from this conference to update the significance of the discrepancy. The " f D s puzzle " stands now at 3.5σ , with σ predominantly from th...

Recent measurements of the branching fraction for Ds → lν disagree with the Standard Model expectation, which relies on calculations of fDs from lattice QCD. This paper uses recent preliminary measurements from CLEO and a new preliminary lattice-QCD result from this conference to update the significance of the discrepancy. The “ fDs puzzle” stands now at 3.5σ , with σ predominantly from the sta...
متن کاملA review of charm semileptonic decays
The semileptonic decays of charm particles continue to be an important area of research. The branching fractions provide measurements of CKM matrix elements in the charm sector, |Vcq| . All hadronic complications are contained in the form factors, which can be calculated via nonperturbative lattice QCD, Heavy Quark Effective Theories, Quark Models, and other methods. By comparing experimental o...
متن کاملData Envelopment Analysis from simulation on the Lattice QCD using CCR model
One of the most serious principles in production theory in economic is the principle of "efficiency". Simply put, efficiency can be defined as the demand that the desired goals (outputs) are achieved with the minimum use of the available resources (inputs). In order to, distinguish the relative efficiency of organizational units with multiple inputs to produce multiple outputs, "Data Envelopmen...
متن کاملFinal State Interaction Effects in B+→J/ψ π+ Decay
In this research the exclusive decay of is calculated by QCD factorization (QCDF) method and final state interaction (FSI). First, the decay is calculated via QCDF method. The result that is found by using the QCDF method is less than the experimental result. So FSI is considered to solve the decay. For this decay, via the exchange of mesons are chosen for the intermedi...
