Nucleon electromagnetic form factors from lattice QCD
It is imperative that lattice QCD serve to develop our understanding of hadron structure and, where possible, to guide the interpretation of experimental data. There is now a great deal of effort directed at the calculation of the electroweak form factors of the nucleon, where for example, measurements at Jefferson Laboratory have recently revealed surprising behaviour in the ratio GE/GM. While...

متن کاملPhenomenology from lattice QCD ∗
The lattice formulation of quantum field theory, combined with large scale numerical simulations, is contributing in a variety of ways to the current research effort in particle physics. In the present talk I will focus on lattice QCD and its rôle in quantifying non-perturbative strong interaction effects. I wish to apologize straight away to those colleagues whose work I will not be able to co...
متن کاملDlν from Lattice QCD
where w = v · v and G(1) = 1. At zero recoil (w = 1) heavy-quark symmetry requires FB→D∗(1) to be close to 1. So, |Vcb| is determined by dividing measurements of dΓ/dw by the phase space and well-known factors, and extrapolating to w → 1. This yields |Vcb|FB→D∗(1), and FB→D∗(1) is taken from “theory.” To date models [ 1] or a combination of a rigorous inequality plus judgment [ 2] have been use...
