The authors present a new constraint on the strongly interacting Higgs sector by analyzing the precision weak-interaction measurements. They show that an integral \( S \) over the spectral function of spin-1 states in the Higgs sector is constrained by these measurements. Current data excludes large technicolor models, and future experiments at LEP and SLC will provide more stringent limits on Higgs strong interactions. The analysis is based on the general formalism for weak interaction radiative corrections, focusing on the vacuum polarization amplitudes. They define parameters \( S \) and \( T \) to constrain the isospin-asymmetric and isospin-symmetric contributions to the Higgs sector, respectively. In technicolor models, \( S \) is estimated to be proportional to the total number of weak doublets, while \( T \) is less reliable but still suggests a large contribution. Combining weak-interaction measurements, they find a 90% confidence upper limit on \( S \) of 3.6, which excludes models with two generations of technifermions but not those with a single generation. Future measurements of polarization asymmetry and forward-backward asymmetry at LEP and SLC will provide more precise constraints on the Higgs strong interactions.The authors present a new constraint on the strongly interacting Higgs sector by analyzing the precision weak-interaction measurements.
