Description |
I will review the recent development of the lattice QCD calculation for strangeness electric and magnetic form factors in the nucleon. The strangeness calculation generally requires the evaluation of the so-called disconnected insertion (DI), which has been a long-standing issue in the lattice simulation. I discuss the methodology which significantly improves the signal for the DI calculation, and present the results from $N_f=2+1$ full QCD lattice simulation. I also report the study of the lowest moments of the strangeness parton distribution function of the nucleon, $\langle x \rangle, \langle x^2 \rangle$. |
