Query: A novel formulation of the unintegrated gluon distribution for DIS   We provide a semi-classical description of the inclusive gluon induced Deep
Inelastic Scattering cross section in a way that accounts for the leading
powers in both the Regge and Bjorken limits. Our approach thus allows a
systematic matching of small and moderate $x_{\rm Bj}$ regimes of gluon proton
structure functions. We find a new unintegrated gluon distribution with an
explicit dependence on the longitudinal momentum fraction $x$ which entirely
spans both the dipole operator and the gluonic Parton Distribution Function.
Computing this gauge invariant gluon operator on the lattice could allow to
probe the energy dependence of the saturation scale from first principles.
