present a theoretical framework to match transverse momentum dependent parton distribution functions (TMD PDFs) onto chiral perturbation theory operators. In this framework, the TMD PDF is expressed as a convolution of TMD hadronic splitting functions, which
describe fluctuations into intermediate hadrons in chiral perturbation theory, and short distance matching coefficients, which are the TMD PDFs of intermediate hadrons in the chiral limit. I explore the various limits of the matching condition and apply an
operator product expansion to the high energy matching coefficients, allowing them to be written in terms of the collinear valence PDFs of intermediate hadrons. As an example, I calculate the isovector TMD hadronic splitting functions for the nucleon at leading
order in the chiral expansion. Finally, I present numerical results and discuss phenomenological implications.</span><span data-ogsc="rgb(32, 32, 32)" data-ogsb="rgb(255, 255, 255)" style="font-family: Calibri, Helvetica, sans-serif, serif, EmojiFont; font-size: 11pt; line-height: 1.5;"> </span></p>
