Electric quadrupole and magnetic octupole moments of the Delta
G. Ramalho, M. T. Pena, Franz Gross
Using a covariant spectator constituent quark model we predict an electric quadrupole moment -0.043 efm^2 and a magnetic octupole moment -0.0035 efm^3 for the Delta+ excited state…

Valence quark contribution for the gamma N -> Delta quadrupole transition extracted from lattice QCD
G. Ramalho, M. T Pena
Starting with a spectator quark model developed for the nucleon (N) and the Delta in the physical pion mass region, we extend the predictions of the reaction gamma N -> Delta to th…
