We calculate the leading twist pion unpolarized transverse momentum distribution f1(x,kT2) and the Boer-Mulders function h1^⊥(x,kT2), using leading Fock-state light front wave functions (LF-LFWFs) based on Dyson-Schwinger and Bethe-Salpeter equations. These DS-BSEs based LF-LFWFs provide dynamically generated s- and p-wave components, which are indispensable in producing chirally odd Boer-Mulders function that has one parton spin flipped. Employing a non-perturbative SU(3) gluon rescattering kernel to treat the gauge link of the Boer-Mulders function, we thus obtain both TMDs at hadronic scale and then evolve them to the scale of μ2=4.0 GeV2. We finally calculate the generalized Boer-Mulders shift and find it to be in agreement with the lattice prediction.
