Constraints to Grand Unified Preon Models from Recent Lep data

  • Constraints to grand unified preon models from recent LEP data on light neutrino species Nv are analyzed.Because the precise experimental result prsult prefers Nv=3,the possible grand unified preon models are grand unified preon models with confining weak interaction.So the weak interaction is confining and is the residual effect of the hypercolor interaction between preons.The constraints to grand unified preon models from the very heavy neutrinos being allowed is also discussed.

Abstract: Constraints to grand unified preon models from recent LEP data on light neutrino species Nv are analyzed.Because the precise experimental result prsult prefers Nv=3,the possible grand unified preon models are grand unified preon models with confining weak interaction.So the weak interaction is confining and is the residual effect of the hypercolor interaction between preons.The constraints to grand unified preon models from the very heavy neutrinos being allowed is also discussed.
