Conclusion (3) on page 8 is incorrect.It should be replaced by the following: 3) Our best guess (assuming SU(2) symmetry) for the masses of fourth generation quarks Q is > 150 GeV.Such quarks may be produced in pp or pc colliding-beam experiments.For example for Ecms 2 2 TeV one might expect a QQ production cross section in the nanobarn range.Such a superheavy quark will decay into a light quark q and an intermediate boson W Q---q+W I s+c leading to a final state typically containing six high-p1 jets (pli N 50 GeV) of unmistakable signature.
