### Description

We’ll present the first lattice QCD calculation of transverse momentum dependence wave function of pion using large momentum effective theory. We use the clover fermion action on three ensembles with $2+1+1$ flavors of highly improved staggered quarks (HISQ) action, generated by MILC collaboration, at pion mass $670MeV$ and $0.12 fm$ lattice spacing, choose three different hadron momenta $P_z=\{1.72, 2.15, 2.58\}$ GeV. Our calculations includes light-front wave function, form factor, Collins-Soper kernel, and soft function. For wave function, we use non perturbative renormalization in MSbar scheme by using Wilson-loop renormalization. We find the curve of wave function with transverse momentum dependence has two turning points, which normal wave function doesn’t.
