Outline of Final Research Achievements |
Conventional particle physics models based on string theory can not answer to very fundamental questions such as "Why are there three generations of quarks and leptons in nature?" To overcome this difficulty, base on the fact that the exceptional group coset E7/((SU(5)×U(1)^3 includes precisely three sets of 10+5*+1 representations of SU(5), we have considered a F-theory compactification in which such a coset spectrum is locally achieved by string junctions near a multiple singularity, to implement the idea of "family unification" in string theory.
