$\mathbf{γ^{(*)} + N(940)\frac{1}{2}^+ \to N(1520)\frac{3}{2}^{-}}$ 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$\,\ot…
