Mixing Matrix of Quarks Having Natural Twisting in E6 Grand Unified Model


Mass matrices of quarks are studied in the Supersymmetric E6 GUT. After decomposition into SU(5), there are two 5 representations in each generation, which consist of the lepton doublet and the right-handed down-type quarks. It is known that the observed quark and lepton mixing matrices could be reproduced well if an appropriate interchange (twisting… (More)
