Open full text 2 citations

Abstract

Masses of the lowest lying hadrons and the behavior of constituent quarks are discussed on the analysis of their electromagnetic properties, based on QCD. We find that light quarks (u and d) in the hadrons move with the velocity ≃0.8c; s quark, with ≲0.7c; c quark, with nearly 0.3c. Then we know that the confinement force, no matter what kind of confinement one prefers, does not mainly contribute to the hadron masses. It is also conjectured that |νe-e|/|u-d|≃|νµ-µ|/|c-s|≃|ντ-τ|/|t-b| and mt≃23GeV on the assumption of the existence of the next layer.
