Abstract

We study the EinsteinYangMills theory which has a classical solution of instantonmonopole configuration on an internalCP N space and leads to a fourdimensional effective gauge theory with an isometry groupSUN+1 We derive the generalized Dirac quantization condition in the presence of instanton monopole so that the fermion is well accommodated in the isotropy group with a nontrivial representation associated with an instanton monopole After harmonic expansions we look for a chirally isolated fermion representation and derive a theorem to obtain a massless fermion Several examples which satisfy the anomalyfree condition are studied It is shown thatSO14 andSO18 gauge theories give spectra of generation numbers 1 3 7 … and 1 5 … of16L inSO10 respectively We also study examples fromE8⊗E8 superstring theorySi studia la teoria di Einstein e YangMills che ha una soluzione classica della configurazione instantonemonopolo su uno spazio internoCP N e porta ad una teoria di gauge efficace quadridimensionale con un gruppo di isometriaSUN+1 Si deriva la condizione di quantizzazione di Dirac generalizzata in presenza di istantonemonopolo cosicché il fermione è ben sistemato nel gruppo di isometria con una rappresentazione non rudimentale associato con un istantonemonopolo Dopo sviluppo armonico si cerca una rappresentazione fermionica isolata in maniera chirale e si deriva un teorema per ottenere un fermione senza massa Si studiano molti esempi che soddisfano la condizione senza anomalie Si mostra che le teorie di gaugeSO14 eSO18 danno spettri di numeri di generazione 1 3 7… e 1 5… di16L inSO10 respettivamente Si studiano anche esempi dalla teoria di superstringE8⊗E8
