Pseudo-scalar meson quark distributions within the Dyson-Schwinger approach

We calculate the impulse approximation to the quark distributions in the pion and kaon using the Dyson-Schwinger/Bethe-Salpeter equation approach. The Mellin moments of the distribution functions are calculated from the forward matrix elements of twist-two operators and are used to reconstruct the quark distribution functions. The meson distribution amplitudes are also calculated from the corresponding moments of helicity-flip twist-two operators.
