摘要
We give a path integral prescription for the pair correlation function of Wilson loops lying in the world volume of D-branes in the bosonic open and closed string theory. The results can be applied both in ordinary hat spacetime in the critical dimension d or in the presence of a generic background for the Liouville field. We compute the potential between heavy nonrelativistic sources in an Abelian gauge theory in relative collinear motion with velocity v = tanh(u), probing length scales down to r(min)(2) = 2 pi alpha'u. We predict a universal -(d -2)/r static interaction at short distances. We show that the velocity-dependent corrections to the short-distance potential in the bosonic string take the form of an infinite Fewer series in the dimensionless variables z = r(min)(2)/r(2), uz/pi, and u(2).
