      Quark transverse charge densities in the Δ (1232) from lattice QCD 

      Alexandrou, Constantia; Korzec, T.; Koutsou, Giannis; Lorcé, C.; Negele, J. W.; Pascalutsa, V.; Tsapalis, Antonios; Vanderhaeghen, M. (2009)
      We extend the formalism relating electromagnetic form factors to transverse quark charge densities in the light-front frame to the case of a spin-3/2 baryon and calculate these transverse densities for the Δ (1232) isobar ...

      Δ-baryon electromagnetic form factors in lattice QCD 

      Alexandrou, Constantia; Korzec, T.; Koutsou, Giannis; Leontiou, Theodoros; Lorcé, C.; Negele, J. W.; Pascalutsa, V.; Tsapalis, Antonios; Vanderhaeghen, M. (2009)
      We develop techniques to calculate the four Δ electromagnetic form factors using lattice QCD, with particular emphasis on the subdominant electric quadrupole form factor that probes deformation of the Δ. Results are presented ...
