The Collins-Soper kernel from a vacuum soft function
Anthony Francis, C. -J. David Lin, Wayne Morris +1
The Collins-Soper kernel is calculated from a vacuum soft function using space-like Wilson lines with complex-directional vectors on the Euclidean lattice. Our pure gauge calculati…
Extracting the distribution amplitude of pseudoscalar mesons using the HOPE method
S. -P. Alex Chang, William Detmold, Anthony V. Grebe +4
The pseudoscalar meson light-cone distribution amplitudes (LCDAs) are essential non-perturbative inputs for a range of high-energy exclusive processes in quantum chromodynamics. In…
Measurement of the TMD soft function on the lattice using the auxiliary field representation of the Wilson line
Anthony Francis, Issaku Kanamori, C. -J. David Lin +2
The transverse momentum dependent (TMD) soft function and Collins-Soper (CS) kernel may be obtained by formulating the Wilson line in terms of auxiliary one-dimensional fermion fie…
The lattice extraction of the TMD soft function using the auxiliary field representation of the Wilson line
Anthony Francis, Issaku Kanamori, C. -J. David Lin +2
The TMD soft function can be obtained by formulating the Wilson line in terms of auxiliary 1-dimensional fermion fields on the lattice. In this formulation, the directional vector…
