Description
In this talk I will show our calculations of Collins-Soper kernel and soft function on a newly generated 2+1 flavor clover fermion CLS ensemble of size $48^4$ with $a=0.098$ fm. The light sea quark mass corresponds to a pion mass of 333 MeV for this ensemble and the valence quark mass to 662 MeV. We measure the large-momentum-transfer meson form factors and its transverse-momentum-depdent wave functions at momenta up to $P^z=12\frac{2\pi}{L}$. The Collins-Soper kernel and soft function are extracted from them using next-to-leading-order factorization based on large-momentum effective theory. Our results are in good agreement with literature.
