Abstract

After a short reminder of the historical role of the quark model as an ancestor of QCD we discuss some of its old and recent achievements and its limitations. We first outline the rather successful description of electroweak hadronic matrix elements, and of strong decays. We also discuss its theoretical weaknesses (non relativistic hypothesis, difficulty to described Goldstone bosons…). We stress that in some fields it remains the only phenomelogical tool: high order hadronic phenomena, processes involving excited hadrons, etc. Finally we exhibit cases in which the successes of the quark model can be understood by more rigorous proofs of the same results.
