On the nature of the Roper resonance
arXiv:1011.0609
Abstract
The lightest N* state, N(1440) P11, also known as Roper resonance, has puzzled physicists for decades. A large variety of theoretical models aimed to understand its properties have been proposed. Some of them are briefly reviewed here, together with the hadronic processes where the Roper resonance is revealed or plays an important role.
