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 $(5.76\mbox{ fm})^3$.
