Pion fragmentation functions from a quark-jet model in a functional approach
Roberto Correa da Silveira, Fernando E. Serna, Bruno El-Bennich
The elementary fragmentation function that describes the process is predicted applying crossing and charge symmetry to the cut diagram of the pion valence quark distributi…

The quark gap equation in light-cone gauge
Roberto Correa da Silveira, Fernando E. Serna, Bruno El-Bennich
We calculate the quark self-energy correction in light-cone gauge motivated by distribution amplitudes whose definition implies a Wilson line. The latter serves to preserve the gau…
