On non-relativistic $Q\bar Q$ potential via Wilson loop in Galilean   space-time
  We calculate the static Wilson loop from string/gauge correspondence to obtain the $Q\bar Q$ potential in non-relativistic quantum field theory, i.e. CFT with Galilean symmetry. We analyze the convexity conditions \cite{bachas} for $Q\bar Q$ potential in this theory, and obtain restrictions for the acceptable dynamical exponent $z$.
