Summary

The branching ratios of\(Z^0 \to f\bar f\) and the second neutral vector boson\(Z^{0'} \to f\bar f\) are found and compared in the\(\bar 8_L + \overline {28} _L + 56_L \) model of theSU8 multigenerational grand unification, where symmetry breakings occur in stepsSU8SU3,G×SU5,F×UI,CSU3,G×SU3,C×SU2,L×U1,B×U1,CSU3,C×SU2,L×U1,YSU3,C×U1,E.

Riassunto

Si trovano i rapporti tra probabilità di decadimento di\(Z^0 \to f\bar f\) e il secondo bosone vettoriale neutro\(Z^{0'} \to f\bar f\) e si confrontano nel modello\(\bar 8_L + \overline {28} _L + 56_L \) della grande unificazione multigenerazionaleSU8, dove le rotture di simmetria avvengono in passi successiviSU8SU3,G×SU5,F×UI,CSU3,G×SU3,C×SU2,L×U1,B×U1,CSU3,C×SU2,L×U1,YSU3,C×U1,E.
