The sensitivity to new physics of a LEP scan in 1995

Abstract

We study the implications of possible off-peak measurements in the 1995 LEP run, in regard to probing physics beyond the Standard Model. To do so, we determine the accuracy with which various nonstandard couplings can be expected to be measured in the three different scan scenarios recently discussed by Clarke and Wyatt. We find that each scan scenario allows greater sensitivity to a different set of new physics couplings. Oblique parameters are best measured with the longest scan, while nonstandard fermion couplings to the Z0 tend to be better constrained (albeit only marginally) if all of the 1995 LEP measurements are taken on the Z0 peak.
