Constraints on a fourth generation of fermions from Higgs Boson searches.

Lenz, Alexander (2013) 'Constraints on a fourth generation of fermions from Higgs Boson searches.', Advances in high energy physics., 2013 . p. 910275.


We review the past and current status of the extension of the standard model (SM) by a fourth generation of fermions. In particular the new results for Higgs boson searches at the LHC and at Tevatron exclude the possibility of having simply a perturbative fourth generation of fermions with one Higgs doublet (SM4). We also briefly mention more complicated extensions of the SM4, which are not yet excluded, like adding in addition another Higgs doublet to the SM4.
