We present an innovative approach to the linearly polarized gluons confined inside the unpolarized nucleon in lepton-nucleon scattering. Our method analyzes the correlation of energy flows at azimuthal separations $\phi$.The interference of the spinning gluon with both positive and negative helicities translates into a $\cos(2\phi)$ asymmetry imprinted on the detector. Unlike the conventional...

In view of the increasing precision of theoretical calculations and experimental measurements, power corrections to transverse-momentum-dependent observables have become highly important. Power corrections for TMD observables are a rich and complex subject, and are difficult to grasp even in the most simple scenarios. Our goal is to understand TMD factorization at next-to-leading power for a...

We develop a theoretical framework to match Transverse Momentum Dependent (TMD) PDFs onto chiral effective theory operators. A convolution formula is presented between TMD hadronic splitting functions and the high energy matching coefficients, which are identified to be the TMD PDFs of intermediate hadrons in the chiral limit. An operator product expansion is applied to the high energy TMD...
