“…This is particularly useful for the present status of our work, because we still have not computed the operator renormalization, while the renormalization factors for the local bilinear quark operators are known: Z V = 0.625(2), Z A = 0.7556 (5), and Z T = 0.7483 (6) in the MS scheme, at µ = 2 GeV, where we used the renormalization functions from Ref. [44], which have also been employed for other nucleon structure quantities [7,45].…”

We provide an analysis of the x dependence of the bare unpolarized, helicity, and transversity isovector parton distribution functions (PDFs) from lattice calculations employing (maximally) twisted mass fermions. The x dependence of the calculated PDFs resembles the one of the phenomenological parameterizations, a feature that makes this approach very promising. Furthermore, we apply momentum smearing for the relevant matrix elements to compute the lattice PDFs and find a large improvement factor when compared to conventional Gaussian smearing. This allows us to extend the lattice computation of the distributions to higher values of the nucleon momentum, which is essential for the prospects of a reliable extraction of the PDFs in the future.

“…Therefore, lattice QCD computations have focused on moments of PDFs, form factors and related quantities. The calculations have been very successful with important results connecting to phenomenology and experiment, see [1,2,3,4,5] for recent reviews and [6] for an overview of lattice activities on hadron structure.…”
