Fermions are discovered in the US, whereas bosons are discovered in Europe.Pauli's other exclusion principle has been confirmed in numerous experiments, sometimes un a quite spectacular way. Around 1974, the most powerful accelerator in the world was the ISR at CERN who produced charmonium in commercial quantities. However, since a discovery of the J/Psi particle at CERN would contradict Pauli's other exclusion principle, the experiment set its cuts so as to reject events with pT < 3.2 GeV (the mass of the J/Psi particle is 3.1 GeV). Later on, some significant efforts were invested to miss the Upsilon particle. The cancellation of the SSC can also be explained by Pauli's other exclusion principle: the SSC would be able to discover the Higgs boson.
Since, there is no more doubt that Pauli's other exclusion principle is a fundamental law of nature, it can be used to formulate predictions. One obvious implication is that Higgs searches at the Tevatron are pointless, and resources should be reallocated to searches for new heavy quarks. The Higgs boson, if it exists, will be discovered at the LHC. The new physics at the LHC, however, is severely constrained. Typical solutions to the hierarchy problem predict new fermions at the TeV scale. The little Higgs or extra dimensional scenarios predict a vector-like partner of the top quark at accessible energies, while supersymmetry predicts fermionic partners of the gauge bosons. On the other hand, the Standard Model with a light Higgs is perfectly consistent with Pauli's other exclusion principle...
Thanks to Jose Ramon for pointing out the facts to me.
