objective wilson disease (wd) is an inherited copper metabolism dysfunction disease characterized by cirrhosis and cns findings. wilson disease is important because it is fatal if not recognized and treated. our goal of study is to investigate the clinical signs and symptoms, lab results and other relevant matters in our patients in order to obtain a better understanding of this potentially let...

The QQ̄ semirelativistic interaction in QCD can be simply expressed in terms of the Wilson loop and its functional derivatives. In this approach we present the QQ̄ potential up to order 1/m2 using the expressions for the Wilson loop given by the Wilson Minimal Area Law (MAL), the Stochastic Vacuum Model (SVM) and Dual QCD (DQCD). We confirm the original results given in the different frameworks a...

I analyse the problem of introducing the spin of the quark and the antiquark in effective QCD strings from the point of view of the Wilson loop for a spin-half particle, or the Super Wilson loop. A string representation of the Super Wilson loop is obtained starting from an effective string representation of a Wilson Loop. The action obtained in this manner is invariant under a worldline supersy...

Numerical experiments on most gauge theories coupled with matter failed to observe string-breaking effects while measuring Wilson loops only. We show that, under rather mild assumptions, the overlap of the Wilson loop operator with the broken-string state obeys a natural upper bound implying that the signal of string-breaking is in general too weak to be detected by the conventional updating al...

I consider a lattice model of a gauge field interacting with matrixvalued scalars in D dimensions. The model includes an adjustable parameter σ, which plays role of the string tension. In the limit σ = ∞ the model coincides with Kazakov-Migdal’s “induced QCD”, where Wilson loops obey a zero area law. The limit σ = 0, where Wilson loops W (C) = 1 independently of the size of the loop, correspond...

The stochastic vacuum model description of a heavy meson is discussed in the context of a gauge-invariant approach where Wilson loop expectation values appear naturally in the O(v 2) spin-orbit Hamiltonian. These expectation values have been derived elsewhere, however by a procedure whose legitimacy is now placed in question. Here they are derived by standard functional methods with a result th...
