Precision "Measurements" of the $Q\bar{Q}$ Potential in MQCD

Abstract

We compute the M theory corrections to the confining linear potential between a quark and an anti-quark in N=1 Super Yang-Mills theory. We find a constant term, and a term exponentially small with characteristic length of ${\Lambda }_{QCD}^{-1}$. The potential in the MQCD setup that corresponds to softly broken N=1 SYM is found to have a similar behavior.
