Macroscopic strings as heavy quarks in large N gauge theory and Antide Sitter supergravity
 PHYS. J. C22
"... Maldacena has put forward large N correspondence between superconformal field theories on the brane and antide Sitter supergravity in spacetime. We study some aspects of the correspondence between N = 4 superconformal gauge theory on D3brane and maximal supergravity on adS5 × S5 by introducing mac ..."

for macroscopic string in antide Sitter supergravity. As a byproduct we clarify how Polchinski’s Dirichlet and Neumann open string boundary conditions arise. We then study nonBPS macroscopic string antistring pair configuration as physical realization of heavy quark Wilson loop. We obtain Q ¯ Q static

1. NRQCD AND THE WILSON LOOP FORMALISM
, 1998
"... Starting from the NRQCD Lagrangian the heavy quarkantiquark potential is written in terms of field strength insertions on a static Wilson loop. The relevant matching coefficients are given at the present status of knowledge. The shortrange, perturbatively dominated, behaviour of the spindependent ..."

Pair Correlation Function of Wilson Loops
, 1999
"... We give a path integral prescription for the pair correlation function of Wilson loop observables on the worldvolume of a Dbrane in the bosonic string theory in flat spacetime. We determine the coefficient of the 1/R term in the static heavy quark potential from the static pair correlation function ..."

relativistic interaction in the Wilson loop approach
"... INTRODUCTION The dynamics of a system composed by two heavy quarks is well understood in terms of a potential interaction (static plus relativistic corrections) obtained from the semirelativistic reduction of the QCD dynamics [1,2,3,4,5]. If at least one of the quarks is light the system behaves re ..."

Heavy Quarkonium Potential and inclusive decay widths in terms of Wilson loops
, 2002
"... We briefly summarize some results obtained by potential NRQCD in the non perturbative regime: 1) a systematic procedure to obtain the heavy quarkonium potential in the 1/m expansion (with explicit expressions up to O(1/m 2) in terms of Wilson loops), and 2) a description of the heavy quarkonium incl ..."

Perturbative Wilson loops with massive sea quarks on the lattice

In particular, the plaquette, the static potential and the static self energy are calculated to this order for massive Wilson, SheikholeslamiWohlert and KogutSusskind fermio ..."

Fidelity and Wilson loop for quarks in confinement region

"... Connection between the stability of quantum motion in random fields and quark confinement in QCD is investigated. The analogy between the fidelity and the Wilson loop is conjectured, and the fidelity decay rates for different types of quark motion are expressed in terms of the parameters which are c ..."
