Query: TMD PDFs in the Laguerre polynomial basis   We suggest the modified matching procedure for TMD PDF to the integrated PDF
aimed to increase the amount of perturbative information in the TMD PDF
expression. The procedure consists in the selection and usage of the
non-minimal operator basis, which restricts the expansion to desired general
behavior. The implication of OPE allows to systematic account of the higher
order corrections. In the case of TMD PDF we assume the Gaussian behavior,
which suggests Laguerre polynomial basis as the best for the convergence of
OPE. We present the leading and next-to-leading expression of TMD PDF in this
basis. The obtained perturbative expression for the TMD PDF is valid in the
wide region of $b_T$ (we estimate this region as $b_T\lesssim 2-3$ GeV$^{-1}$
depending on $x$).
