  We study ridge correlations of the glasma in pp collisions at
$\sqrt{s_{\mathrm{NN}}}=7$ TeV by using the color glass condensate (CGC)
formalism. The azimuthal collimation at long range rapidity is intrinsic to
glasma dynamics and is reproduced here. When rapidity window enlarges, ridge
correlations in two dimensional $\Delta y$-$\Delta\phi$ distribution and one
dimensional $\Delta\phi$ distribution at long range rapidity gap are enhanced.
The enhancements are demonstrated to be the contributions of source gluons. The
quantum evolution of the gluons presents unique correlation patterns in
differential correlation function. These characters of two gluon correlations
open a way of testing the production mechanism from experimental measurements.
