Query: Nucleon Tomography and Generalized Parton Distribution at Physical Pion
  Mass from Lattice QCD   We present the first lattice calculation of the nucleon isovector unpolarized
generalized parton distribution (GPD) at the physical pion mass using a lattice
ensemble with 2+1+1 flavors of highly improved staggered quarks (HISQ)
generated by MILC Collaboration, with lattice spacing $a\approx 0.09$~fm and
volume $64^3\times 96$. We use momentum-smeared sources to improve the signal
at nucleon boost momentum $P_z \approx 2.2$ GeV, and report results at nonzero
momentum transfers in $[0.2,1.0]\text{ GeV}^2$. Nonperturbative renormalization
in RI/MOM scheme is used to obtain the quasi-distribution before matching to
the lightcone GPDs. The three-dimensional distributions $H(x,Q^2)$ and
$E(x,Q^2)$ at $\xi=0$ are presented, along with the three-dimensional nucleon
tomography and impact-parameter--dependent distribution for selected Bjorken
$x$ at $\mu=3$ GeV in $\overline{\text{MS}}$ scheme.
