Mesones PION, RHO y los Diquarks: factores de forma
(Universidad Michoacana de San Nicolás de Hidalgo, 2012-08)
We present results of the static and electromagnetic properties of the pseudo-mescal mesons, vector and diquarks correlations based in a contact interaction. A basic motivation of this study is the need to document a ...
Estudio de un modelo relativista de quark-diquark para el nucleón y sus resonancias
(2011)
En este trabajo se desarrolla un modelo de quarks constituyente para el nucleón y sus resonancias utilizando la aproximación quark-diquark para describir las propiedades de este estado ligado. Específicamente se intentará ...
Masa de mesones y bariones: un tratamiento unificado
(Universidad Michoacana de San Nicolás de Hidalgo, 2021-02)
This work shows how the masses of hadrons composed of quarks u, d, s, c and b are calculated in a model called Contact Interaction (CI). The mathematical basis for this analysis is implemented through the use of CI in the ...
Resonant production of scalar diquarks at the next generation electron-positron colliders
(Iop Publishing Ltd, 2004-06-01)
We investigate the potential of TESLA and JLC/NLC electron-positron linear collider designs to observe diquarks produced resonantly in processes involving hard photons.
A diquark model for baryon spectroscopy
(1993-06-01)
A quark-diquark approximation is used to investigate the mass spectroscopy of the spin-1/2 baryons belonging to the SU(3)-flavor group in a nonrelativistic potential approach. The baryon spectra obtained are confronted ...
A study of a relativistic quark-diquark model for the nucleon
(Springer, 2014-11-11)
We develop a specific quark-diquark constituent model for the study of the nucleon and its excited states. A relativistic kinetic energy operator is used for both the quark and the diquark. Interaction terms depending on ...
Diquarks and nucleons under strong magnetic fields in the NJL model
(American Physical Society, 2020-11)
We study the description of nucleons and diquarks in the presence of a uniform strong magnetic field within the framework of the two-flavor Nambu–Jona-Lasinio model. Diquarks are constructed through the resummation of quark ...
Electromagnetic form factors of nucleons in a light-cone diquark model
(PUBLISHED FOR THE AMERICA PHYSICAL SOCIETY BY THE AMERICAN INSTITUTE OF PHYSICS, 2002)
T-odd quark-gluon-quark correlation function in the diquark model
