Analysis of the quadrupole deformation of Δ(1232) within an effective Lagrangian model for pion photoproduction from the nucleon
Fernández Ramírez, C.; Moya de Guerra, E.; Udías, J. M. (Springer New York, 2017-03)We present an extraction of the E2/M1 ratio of the Δ(1232) from experimental data applying an effective Lagrangian model. ...

Helicity dependence and contribution to the Gerasimov-Drell-Hearn sum rule of the γ d → π NN reaction channels in the energy region from threshold up to the (1232) resonance
Darwish, E. M.; Fernández Ramírez, C.; Moya de Guerra, E.; Udías, J. M. (American Physical Society, 2007-10)The helicity dependence of the γ d→π−pp, γ d→π+nn, and γ d→π0np reaction channels is studied for incident photon ...

Hints on the quadrupole deformation of the (1232)
Fernández Ramírez, C.; Moya de Guerra, E.; Udías, J. M. (American Physical Society, 2006-04-24)The E2/M1 ratio (EMR) of the (1232) is extracted from the world data in pion photoproduction by means of an effective ...
