Screening Masses for Scalar and Pseudoscalar Mesons and their Diquark Partners: Insights from the Contact Interaction Model
M. A. RamÃrez-Garrido, R. J. Hernández-Pinto, I. M. Higuera-Angulo +1
In this study, we calculate the screening masses of forty spin-zero meson and diquark states composed of light, heavy and heavy-light quarks, within a symmetry-preserving framework…

Electric, Magnetic and Quadrupole Form Factors and Charge Radii of Vector Mesons: From Light to Heavy Sector in a Contact Interaction
R. J. Hernández-Pinto, L. X. Gutiérrez-Guerrero, M. A. Bedolla +1
We present a detailed survey of electric, magnetic and quadrupole form factors of light and heavy spin-1 vector mesons. It complements our analogous analysis of the electromagnetic…

First Radial Excitations of Baryons in a Contact Interaction: Mass Spectrum
L. X. Gutiérrez-Guerrero, Alfredo Raya, L. Albino +1
We compute masses of twenty positive parity first radial excitations of spin- and baryons composed of u,d,s,c and b quarks in a quark-diquark picture within a contact in…
