Surface vibrations of the nucleon
Abstract
We examine the dynamics of bag vibrations in a model of the nucleon similar to that of Brown, Durso, and Johnson (BDJ). The model consists of a spherical bag with a variable radius and three quarks confined in it. In addition there is a pion cloud which tends to squeeze the bag. An ad hoc inertial mass is assumed for the bag motion. The Roper resonance is interpreted as due to the breathing mode. Unlike the BDJ calculation, we treat the …
