Neutrino physics: New flavors or charm, then color, excitation
Investigation of charm, then color, excitation through right-handed, color-octet currents is suggested as a more economical way than adding new flavors for avoiding the conflict of the Weinberg-Salam model with present ..nu.. and nu-bar data. The effects from simply adding to the Glashow-Iliopoulos-Maiani current a new right-handed color-octet weak current (the analog of the usual Cabibbo current) are calculated and compared with available charged-current and neutral-current data. A color-octet piece in the weak currents, in general, does not change the lowest-order predictions for the Weinberg-Salam model for (i) elastic and quasi-elastic ..nu..- or nu-bar-nucleon scattering, (ii) neutral-current-induced parity-violating transitions in atomic physics, and (iii) coherent neutrino-nucleus scattering.
