Query: Small-$x$ QCD evolution of $2 n$ Wilson line correlator: the weak field
  limit   We write down explicit expressions for the $x$-evolution (equivalent to
energy or rapidity evolution) of $2 n$ ($n = 1, 2, ...$) Wilson lines using the
JIMWLK equation and the Color Glass Condensate formalism. We investigate the
equation in the weak gluon field limit (linear regime) by expanding the Wilson
lines in powers of the gluon field and show that it reduces to the BJKP
equation describing the evolution of a state of $2 n$ Reggeized gluons with
energy. We also make available for download a {\it Mathematica} program which
provides this expression for any value of $n$.
