# Lattice calculation of hadronic tensor of the nucleon

## Speakers

• Prof. Liu KEH-FEI

## Content

We compute the hadronic tensor $W_{\mu\nu}$ in the Euclidean space by calculating 4-point correlation functions on the lattice, two topologically distinct connected insertons are considered which help to separate the connected sea parton contribution from that of the disconnected sea. We try to convert the Euclidean hadronic tensor to Minkowski space through inverse Laplace transform. As an exploratory study, we use a $12^3\times128$ anisotropic lattice with $a_s\sim 0.18$ fm and $m_{\pi}\sim$ 640 MeV for a range of $Q^2$ and $x$.
