NegativeS and light new physics
Abstract
The several sigma difference between SLD's recent precise measurement ofALR and the corresponding LEP results tends to reinforce the earlier trends in the data towards negative values for the Peskin-Takeuchi parameterS andT. Motivated by this not yet statistically significant, but suggestive, trend, we explore which kinds of new particles can (1) contribute dominantly to new physics through oblique corrections, (2) produce negative values forS …
