Limits on Extensions of the Minimal Standard Model from Combined LEP Lineshape Data
arXiv:hep-ph/9504299 · doi:10.1142/S0217732395001174
Abstract
The high statistics of the combined LEP lineshape data are used to derive constraints on hypothetical extensions of the Minimal Standard Model. The data comprises about eight million visible Z decays, recorded between 1989 and 1993. This letter gives limits for simple tests on models which predict additional Z boson decays or modified Z-couplings. As an application the two-doublet Higgs model is considered.
