Abstract

A class of string models is studied to leading order in a

\frac{1}{d}

expansion, where

d

is the dimensionality of space-time. The static potential is found to be given by

V (R) = M^{2} R {(1 - \frac{{R_{c}}^{2}}{R^{2}})}^{\frac{1}{2}}

, where

R_{c}

is a critical distance. At

R = R_{c}

, the system undergoes a phase transition to a state where a quasistatic string picture is no longer applicable.
