Four-Generation Condensate Scheme Without the Fourth Generation of Leptons
Zhou Bangrong · Communications in Theoretical Physics · 1997
The renormalization group (RG) analyses show that in the four-generation fermion condensate scheme of electroweak symmetry breaking without the extra fourth generation of leptons the limitation to the compositeness scale could be greatly loosened and up to GeV if the masses of the extra fourth generation of quarks are demanded to be bigger than the top-quark mass . However, the mass constraints between the Higgs boson and its constituent -fermions are no longer totally valid for . The predicted masses of the fourth generation of quarks and the Higgs boson will be larger than the corresponding ones in the four-generation quark-lepton scheme. The stability of the results for variation of the compositeness boundary conditions could be explained more clearly.
