摘要：
We study 2 -> n inelastic fermion-(anti)fermion scattering into multiple longitudinal weak gauge bosons and derive universal upper bounds on the scales of fermion mass generation by imposing unitarity of the S matrix. We place new upper limits on the scales of fermion mass generation, independent of the electroweak symmetry breaking scale. Strikingly, we find that the strongest 2 -> n limits fall in a narrow range, 3-170 TeV (with n=2-24), depending on the observed fermion masses.
