Description
We study the small-$x_B$ asymptotics of the leading-twist quark Transverse Momentum Dependent parton distribution functions (TMDs). We apply the recently developed Light Cone Operator Treatment (LCOT) to rewrite the TMD operator definitions at small-$x_B$ in terms of polarized dipole amplitudes, then construct and solve small-$x_B$ evolution equations for the dipole amplitudes in the large-$N_c$, linearized, Double Logarithmic Approximation (DLA). Together with the previous work applying the LCOT to TMDs and the known small-$x_B$ behavior of the unpolarized quark TMD, we have now obtained the small-$x_B$ asymptotics for all eight leading-twist quark TMDs in both the flavor singlet and flavor non-singlet sectors.
