We describe the computation of parton distribution functions (PDFs) of the nucleon from first principles. The investigation is done within the lattice formulation of Quantum Chromodynamics (QCD). The numerical calculations are performed employing a twisted mass ensemble of gauge field configurations simulated with two degenerate light quarks with mass fixed to their physical value. By using the quasi-PDF approach we extract the isovector unpolarized, helicity and transversity distributions. Within this approach, we compute quasi-distributions which are related to the physical PDFs using the framework of Large Momentum Effective Theory. As the nucleon boost increases, we observe that the renormalized lattice PDFs move towards the quark distr...
