摘要

We update the constraints on anomalous dimension four t-b-W and t-t-Z couplings by using CLEO b --> s gamma and LEP/SLC precision Zpole data. it is found that the data imposes very stringent bounds on them. Moreover,the 2 sigma pull from SM predictions of A(LR)(hadrons), A(b) and A(FB)(b) have little chance of being explained by the stron...更多
