Test of nonconfinement through a neutral-current scattering experiment

It is remarked that within the gauge theory of physical color (integer-charge quarks), one expects to see significant rises in neutral-current parameters (≅40-45% in ${\sigma }_{\mathrm{NC}}^{\nu }$, ≅60-65% in ${\sigma }_{\mathrm{NC}}^{\overline{\nu }}$, ≅20% in $R_{\nu }$, and ≅10% in $R_{\overline{\nu }}$ due to color excitation above color threshold. This pattern of rises is characteristic of the color-excitation hypothesis alone; it cannot be attributed to new-flavor excitation within the gauge framework. It is pointed out that within the constraints of renormalizable gauge interactions new-flavor excitation may [under very special circumstances involving an extension of the ${\mathrm{SU}\mathrm{}\left(2\right)\mathrm{}}_w\times \mathrm{U}\mathrm{}\left(1\right)\mathrm{}$ gauge structure] lead to rises in the neutral-current parameters; however, the corresponding pattern of rises (i.e., rises in $\nu N$ versus $\overline{\nu }N$ is distinct from that due to color excitation.
