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…
Dressed quark-gluon vertex form factors from gauge symmetry
Bruno El-Bennich, Fernando E. Serna, Roberto Correa da Silveira +3
We present preliminary results on the longitudinal transverse form factors of the quark-gluon vertex as functions of the incoming and outgoing quark momenta and an angle $θ=2…
Parametric Hamilton's equations for Lagrangian model for passive scalar gradients
L. S. Grigorio
In the context of instanton method for stochastic system this paper purposes a modification of the arclength parametrization of the Hamilton's equations allowing for an arbitrary i…
