$γ^{(*)} + N (940) \frac{1}{2}^{+} \to N (1520) \frac{3}{2}^{-}$ helicity amplitudes and transition form factors

L. Albino, G. Paredes-Torres, K. Raya +2

We recently reported new results on the $γ^{(*)} + N (940) \frac{1}{2}^{+} \to Δ (1700) \frac{3}{2}^{-}$ transition form factors using a symmetry-preserving treatment of a vector$\,\otim…

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 $u, d, s, c$ and $b$ quarks, including states that contain one or…
