Charm and strange meson fragmentation functions
Roberto C. da Silveira, Ian C. Cloët, Bruno El-Bennich +1
Quark fragmentation functions describe the hadronization process of a quark where any of the final-state hadrons carries a fraction of its initial momentum. We compute these fragme…
Charge dependence of mesons with flavored contact-interaction couplings
Fábio L. Braghin, Bruno El-Bennich, Fernando E. Serna
Effective interaction models of quantum chromodynamics, based on quark degrees of freedom, have been successfully employed to compute the properties of a large array of ground and…
Parton distribution and fragmentation functions with massive gluons
Gustavo B. Bopsin, Bruno El-Bennich, Gastão Krein +2
The correct description of the hadron's structure requires understanding how quarks and gluons form the observable hadrons and how they are distributed within them. Two key nonpert…
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…
Parton distribution functions and transverse momentum dependence of heavy mesons
Fernando E. Serna, Bruno El-Bennich, Gastão Krein
The leading Fock state light-front wave functions of heavy quarkonia and and mesons are obtained from the projections of their Bethe-Salpeter wave functions on the light fr…
