Extracting the Omega- electric quadrupole moment from lattice QCD data
G. Ramalho, M. T. Pena
The Omega- has an extremely long lifetime, and is the most stable of the baryons with spin 3/2. Therefore the Omega- magnetic moment is very accurately known. Nevertheless, its ele…
D-state effects in the electromagnetic N-Delta transition
G. Ramalho, M. T. Pena, Franz Gross
We consider here a manifestly covariant quark model of the nucleon and the Delta, where one quark is off-shell and the other two quarks form an on-shell diquark pair. Using this mo…
Electromagnetic form factors of the Delta in a S-wave approach
G. Ramalho, M. T. Pena
Without any further adjusting of parameters, a relativistic constituent quark model, successful in the description of the data for the nucleon elastic form factors and of the domin…
A Covariant model for the nucleon and the
G. Ramalho, M. T. Pena, Franz Gross
The covariant spectator formalism is used to model the nucleon and the (1232) as a system of three constituent quarks with their own electromagnetic structure. The definition of…
