Effects of negative energy components in the constituent quark model

Relativistic covariance requires that in the constituent quark model for mesons the positive energy state as well as the negative energy states are included. Using relativistic quasipotential equations the contribution of the negative energy states is studied for the light and charmonium mesons. It...

Zusammenfassung:Relativistic covariance requires that in the constituent quark model for mesons the positive energy state as well as the negative energy states are included. Using relativistic quasipotential equations the contribution of the negative energy states is studied for the light and charmonium mesons. It is found that these states change the meson mass spectrum significanlty but leave its global structure untouched.
