Description
In this work we present the analysis of Collins-Soper kernel extracted from pion transverse momentum dependent wave functions in the framework of large momentum effective theory from lattice QCD. We use clover fermion action with $2 + 1 + 1$ flavors of highly improved staggered quarks (HISQ), with lattice spacing $a=0.12$fm and volume $L^3\times T=48^3\times64$. The results are obtained based on pion mass $M_{\pi}=670$MeV, and three hadron momenta as $P^z = 2\pi/L\times\{8, 10, 12\} = \{1.72, 2.15, 2.58\}$GeV. Preliminary results are found in consistent with previous LQCD determinations and phenomenological results.
