First Radial Excitations of Mesons and Diquarks in a Contact Interaction
G. Paredes-Torres, L. X. Gutiérrez-Guerrero, A. Bashir +1
We present a calculation for the masses of the first radially excited states of forty mesons and diquarks made up of and quarks, including states that contain one or…
Elastic meson form factors in a unified scheme
R. J. Hernández-Pinto, M. Bedolla-Hernández, L. X. Gutiérrez-Guerrero +1
The extraction of elastic form factors for mesons in the context of the contact interaction model is revisited in this manuscript. The dressed masses of quarks and mesons are deter…
Mesons and Baryons: Parity Partners
L. X. Gutiérrez-Guerrero, G. Paredes-Torres, A. Bashir
We calculate masses of light and heavy mesons as well as baryons of negative parity containing and quarks. It is an extension of our previous work where we had studie…
Mass Spectra of One or Two Heavy Quark Mesons and Diquarks within a Nonrelativistic Potential Model
L. X. Gutiérrez-Guerrero, A. Alfaro, A. Raya
In this article, the mass spectra of mesons with one or two heavy quarks and their diquarks partners are estimated within a non-relativistic framework by solving Schrödinger equati…
Dynamical diquarks in the transition
Khépani Raya, L. X. Gutiérrez-Guerrero, Adnan Bashir +5
The transition is studied using a symmetry-preserving regularisation of a vectorvector contact interaction (SCI). The framewo…
Masses of Light and Heavy Mesons and Baryons: A Unified Picture
L. X. Gutiérrez-Guerrero, Adnan Bashir, Marco A. Bedolla +1
We compute masses of positive parity spin- and baryons composed of , , , and quarks in a quark-diaquark picture. The mathematical foundation for this an…
