Composite scalars at CERN LEP: Constraining technicolor theories

Journal Article · · Physical Review D
CERN LEP I and LEP II data can be used to constrain technicolor models with light, neutral pseudo--Nambu-Goldstone bosons P{sup a}. We use published limits on branching ratios and cross sections for final states with photons, large missing energy, jet pairs, or b{bar b} pairs to constrain the anomalous P{sup a}Z{sup 0}Z{sup 0}, P{sup a}Z{sup 0}{gamma}, and P{sup a}{gamma}{gamma} couplings. From these results, we derive bounds on the size of the technicolor gauge group and the number of technifermion doublets in models such as low-scale technicolor.
