Abstract

All the realistic free fermionic models utilize a set of basis vectors, the NAHE set, that correspond to Z₂× Z₂ orbifold compactification with nontrivial background fields. I argue that the realistic features of free fermionic models, like the number of generations and the fermion mass spectrum are due to the underlying Z₂× Z₂ orbifold compactification.
