Lattice Parton Distribution Functions at Physical Pion Mass

We present the first lattice results on isovector unpolarized, longitudinally and transversely polarized parton distribution functions (PDFs) at physical pion mass. The PDFs are obtained using the large-momentum effective field theory (LaMET) framework where the full Bjorken-$x$ dependence of finite-momentum PDFs, called ``quasi-PDFs'', can be calculated on the lattice. The quasi-PDF nucleon matrix elements are renormalized nonperturbatively in RI/MOM-scheme. We demonstrate the current state-of-the-art of the 2+1+1-flavor lattice data at physical pion mass with lattice spacing 0.09~fm and volume $(5.76\mbox{ fm})^3$.
