Supersymmetric Grand Unification with a Fourth Generation?
arXiv:hep-ph/0305007 · doi:10.1016/j.physletb.2003.06.017
Abstract
The possibility of incorporating a chiral fourth generation into a SUSY-GUT is investigated. Precision fits to electroweak observables require us to introduce light supersymmetric particles, with masses less than mZ. These particles might also provide decay channels for fourth generation quarks of mass ~ 100 GeV. We also require tan(beta) to lie in the range 1.50 <~ tan(beta) <~ 1.75 and obtain an upper limit on the lightest Higgs boson mass in the MSSM4 of 152 GeV.
