Description
One of the most striking phenomena arising from the extension of collinear factorization (inspired in Bjorken's parton model) to Transverse Momentum Dependent (TMD) factorization is the appearance of azimuthal modulation induced by the polarization of partons with nonzero transverse momentum even inside unpolarized hadrons. Linearly polarized gluons inside unpolarized hadrons is one of these cases. We present the pertubative calculation of the matching coefficient onto unintegrated PDF in the limit of large $q_T$ (or small $b_T$) at NNLO in QCD.
