Lattice Predictions for Low Q 2 Phenomenology
Recent results of Monte Carlo simulations for SU(3) lattice gauge theories are used to make quantitative predictions which can be compared with QCD phenomenology. In particular, lattice results are used to predict the onset of nonperturbative effects and to determine the interquark potential. The relationship between A0 and the short distance scale of the qqpotential is also calculated. The pre...
متن کاملPredictions with lattice QCD
In recent years, we used lattice QCD to calculate some quantities that were unknown or poorly known. They are the q dependence of the form factor in semileptonic D → Klν decay, the leptonic decay constants of the D and Ds mesons, and the mass of the Bc meson. In this paper, we summarize these calculations, with emphasis on their (subsequent) confirmation by measurements in ee, γp and p̄p collisions
متن کاملLattice Predictions for the Interquark Potential
The measured values of Wilson loops in Monte Carlo simulations of SU(3) lattice gauge theories are used to predict the qi potential. The relationship between ho and the short distance scale of the qq potential is also calculated. The predictions are in agreement with theoretical expectations but indicate that fermions must be incorporated into the lattice calculations before any realistic resul...
متن کاملLattice Predictions for Hybrids and Glueballs
QCD is a simple elegant theory, but it is hard to solve it using anything other than perturbation theory. Quantities, such as masses, depend on the coupling (g) like M ∼ e 2 [1], hence perturbation theory can’t be used to compute the masses of hadrons such as the proton. Our inability to solve QCD non-perturbatively makes it hard to determine basic parameters of the quark sector of the standard...
متن کاملSome Predictions for an Improved Fermion Action on the Lattice
We propose an improved fermion action on the lattice by adding a next nearest neightbor interaction term to the Wilson action. The proposed action is expected to approach the continuum limit more rapidly. Using the improved action, the predictions for the critical value of the hopping parameter at weak and strong coupling are given. The relationship between quark masses on the lattice and in th...
