  Transverse momentum dependent (TMD) distributions at small x exhibit a rich
infinite twist structure that encompasses the leading twist (partonic)
distributions as well as the physics of gluon saturation. Progress to further
the connection between the standard TMD framework at moderate x and small x has
been recently made. In this context, we show that light cone Wilson line
operators at small-x can be formulated in terms of transverse gauge links. This
new formulation of small x operators allows a direct matching with the standard
leading twist gluon TMD distributions and provides an efficient and general
prescription for computing TMD distributions at small x beyond leading twist.
