Phenomenology from Lattice Qcd

چکیده

I review two subjects in which lattice simulations are making, or can make in the future, a significant contribution to particle physics phenomenology. The first subject is the evaluation of quantities which enter into the determination of the vertex A of the unitarity triangle from experimental measurements of decay rates and mixing amplitudes. These quantities include the form-factors for semileptonic B-decays, the leptonic decay constants of the B and Bs mesons and the B-parameters for B d-¯ B d and Bs-¯ Bs mixing and the corresponding parameter for K-¯ K mixing, B K. In the second part of this talk I will review the status and prospects for the evaluation of K → ππ amplitudes and for the subsequent study of the ∆I = 1/2 rule and the evaluation of ε ′ /ε.

Phenomenology of the Standard Model from Lattice QCD1

Some recent results of lattice QCD calculations which are relevant for the phenomenology of the Standard Model are reviewed. They concern the lattice determinations of quark masses, studies of K−K̄ and B−B̄ mixings, and a prediction of the B s -mesons lifetime difference. The results of a recent analysis of the CKM unitarity triangle, which is mostly based on the lattice calculations of the relev...

Data 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...
