Octet baryon electromagnetic form factors in a relativistic quark model
G. Ramalho, K. Tsushima
We study the octet baryon electromagnetic properties by applying the covariant spectator quark model, and provide covariant parametrization that can be used to study baryon electro…

A simple relation between the gamma N -> N(1535) helicity amplitudes
G. Ramalho, K. Tsushima
It is shown that the helicity amplitudes A_1/2 and S_1/2 in the gamma N -> N(1535) reaction, can be well related by S_1/2 = -\frac{\sqrt{1+τ}}{\sqrt{2}} \frac{M_S^2-M^2}{2 M_S Q} A…
