Abstract
The structure of the nucleon and other baryons can be studied using electro-weak probes. In the last years a significant amount of data were collected in the modern accelerators. To interpret those data it is fundamental the development of theoretical models. Of interest are models based on the quarks and mesons degrees of freedom. In the past, the Covariant Spectator Quark Model (CSQM) was developed for the study of the internal structure of the nucleon and other light baryons based on constituent quarks (quarks with internal structure).The main goal of the project is to keep developing models for other baryons and for different physical conditions. More specifically, we are interested in the following cases: i) baryon in vacuum; ii) inclusion of quark-antiquark effects; iii) model extensions for the timelike region,in order to study resonance N* decays intonucleon (N) and electron-positron pairs (N* -> N e+e-); iv) extension of the model for nuclear medium; v) extension of the model for baryons with heavy quarks (s,c,b).
