New Approach to Center of Mass Motion in Relativistic Quark Models and Electroweak Properties of Hadrons

摘要

It is assumed that a state of an independent quark model describes hadron bound in an external fictitious well of appropriate size rather than a wave packet of free states. A definite prescription connecting hadron formfactors with bound state matrix elements is given. General relations are illustrated by the ''raw'' MIT bag model for nucleon, with no free parameter to fit, leading to very reasonable values of electroweak parameters. 11 refs.
