Abstract: (APS)

We show that an integral S over the spectral function of spin-1 states of the Higgs sector is constrained by precision weak-interaction measurements. Current data exclude large technicolor models; asymmetry measurements at the CERN e+e− collider LEP and the SLAC Linear Collider will soon provide more stringent limits on Higgs-boson strong interactions.

Higgs particle: strong interaction
strong interaction: Higgs particle
electroweak interaction: symmetry breaking
symmetry breaking: electroweak interaction
isospin: asymmetry
asymmetry: isospin
radiative correction
vacuum polarization
Z0: width
Weinberg angle
