Cross-section asymmetries around the Z peak
A simple model-independent formula for cross-section asymmetries A in fermion-pair production is derived, which may be used for the analysis of LEP~1 data, A = \sum_n A_n (s - M_Z^2)^n. The coefficient A_0 depends on the Z boson exchange, A_1 additionally on the \gamma Z interference, while the high...

| description | A simple model-independent formula for cross-section asymmetries A in fermion-pair production is derived, which may be used for the analysis of LEP~1 data, A = \sum_n A_n (s - M_Z^2)^n. The coefficient A_0 depends on the Z boson exchange, A_1 additionally on the \gamma Z interference, while the higher-order contributions are practically redundant. QED corrections are taken into account, and relations to other approaches are indicated. |
